Opinions about SLP

[secondgearscratch]

wasnt sure if this was the right forum but since i have a z here i am. ive heard alot of mixed reviews from people on this site and people i run into around town as to the goodness of SLP. its either been "fuck them, the shit is overpriced and isnt that good", or "i love SLP because its so good."
No real reasons were given to me either way.
Help is appreciated.

[Mr. Luos]

Overpriced.
Old designs.
Horrible customer service. I was actually called a liar by someone from SLP on the phone.

I could get into it. :lol:
I avoid SLP like the plague.
SLP banks on 'rookie modders' for business. They know they can't sell to those that have been around the cars for a while.

totally agree.
ls1 tuners like thunder racing will sell you packages/products that are the same as slp for cheaper.

I had a problem with my wheels in the first year of owning the car(2001 SS). One of my wheels began to peal. I talked to someone at Rick Hendrick Chevrolet in Durham, NC and had a great experience with the customer service there. What I did not like was the long wait for a replacement wheel and the plastic lugnut caps did not match the originals! That PISSED ME OFF! Within the second month the was a hole in my driver's side floor mat. I was told it was not under warrenty and it could have come from the shoes I was wearing. BULLSHIT! The more I think and talk about it the more I am getting upset. ...I gotta go.

[Mr. Luos]

I don't know what that has to do with this thread.

But I understand. :yup:

[WARP211]

It all depends on what you are gonna do to the car.. weather you want it as a daily driver or a weekend warrior.. If you got a warranty on your car.. I would say go with SLP because their are just bolt-ons.. Or anyother company that's just bolt-ons.. Bolt-ons are good way to get power without having to worry if you are gonna break something.. As long as you keep it basic.. I have the cold air ind. kit from SLP and i'm satisfied with it.. Like i said it all depends on what you wanna do..

['96 Z28SS]

their products arent quite top notch, if i was choosing them and someone else i would pick the other guy. i just like the history and such behind it.

[Mr. Luos]

I wouldn't go with SLP for anything but a lid.

Bolt-on or not.

[MSP01SS]

Well I really do like my SLP Longtubes. Okay I said it now I will go back in my corner:sulk:

So what do you guys think about the Headers from SLP..??and other types of headers out their??:thinkin: to Y2kpewterSS, Mr. Lous

[Y2KPewterSS]

SLP headers= bad clearance and overpriced, overhyped

Hooker headers= I have had them before, liked their fit, and priced decently

Jet hots= I currently have them, love the fit, love the price, recommend them

Pacesetters= I have ran them before, great bang for the buck, good fit

Hedman= A friend has them, not impressed with their fit

Mac mids= If you don't plan to cam your car, a definite option to consider, better fit than long tubes, good power, very affordable

These are all the $600 and under headers I can think of.

What about stainless or Kooks.??

Lets talk cat-back system.

SLP LM 11 is a lot less money that GMMG chambered, even thou I know GMMG is better, the money comes in to play somewhere, doesn't it ?

Now I'm talking no headers here, just stock ex. other than cat back.

Does anyone here think GMMG is worth the hundred's more ?

[Rajun Cajun]

I don't know what that has to do with this thread.

But I understand. :yup:

My wheels are from SLP, I thought I should have gotten a better turn around time than 3 weeks. I also thought I should have gotten the original style plastic lug nut caps. I forgot to tell you all that some dumb ass put an impact wrench on the plastic nuts to tighten them and tore 4 of them to shit! Just tires paid for new ones but like I said before, I did not receive the original style caps.

:yup:
and i work for one of "those" companies

[1BADDLS1]

only SLP product i'll own is their LID

best fit
best flow
best looking

SLP LongTubes = :Puke:
the tuned length :lastweek: made sense and a good idea... but the gains are minimal if even measurable
plus you'll rip them out with out being lowered

[Firebirdjones]

Seems to be a few that have had bad experiences with SLP. I personally have not had trouble. Although I have only bought the SLP lid for mine so I haven't dealt with them much. There are a few things I would buy from them simply if it's not available anywhere else. Some of the comemorative paperwork on the SS and WS6 cars is pretty neat, and some of the factory parts unique to SS cars but other than that,,,if it comes to speed parts I would go elsewhere,,,not because of bad experiences,,,but because I already have other connections from playing with other cars and I stay with what I know and I'm happy with.
Keeping in mind it's SLP that helped create these cars that everyone here loves so much. So we can't really knock them too much without being considered hipocrits. Larry.

[Jon7I2]

I can't beleive that they r calling some of u guys liars on the phone. That is completely ridiculous. I just can't imagine. Like how did they call u a liars? Did they ask what current mod's u had, and then they didn't believe u? WOW! that is really bad in my mind. I don't blame anyone for not ever using or recommending any of their products after an experience like that.

[WARP211]

That why their bolt on's.. bolt them in... you can bolt them off too... :thinkin:

[secondgearscratch]

it looks like i'll be steering kinda clear of street legal performance. i appreciate all the feedback as it is extremely usefu because im almost 19, in college and money is not something that shows up in huge numbers. Ive been talking to a few people ive met around town with some really nice f bodies plus everyone on here and i am going to look into texas speed and thunder racing. anyone run or heard about the magic stick 3 cam form tsp? let me know

yeah i heard of of the magic stick.. its a good cam it put up some decent numbers.. you should look in to GM high tech performance.. They did an articule on the magic stick and some of the thuder racing products.. gives you HP#'s and TQ#'s at the wheels not the crank...

[jmhvenom]

I would advise against SLP, only had trouble with them so far. I would definately recommend some of the Thunder (not thuder) racing products a lot of people have seen some good gains. I am a college student myself so I understand the money issues. What mods do you have already, might not need to look at cams yet.

[WARP211]

I seen some one at the track that had the whole SLP PKG.. 400HP one.. with some 4.11 gears.. he ran a consistant 12.5-12.4 and i think he had slicks.. no too sure if he did.. If you don't have that much money or money is an issue with you.. then i would go with cam that should be a good gain and not to much money.. if you install it yourself.. But you'd better know how or else..:nite:

[1BADDLS1]

Thunder Racing & Texas Speed :worship:
excellent info and amazing customer service

MTI & LG are also good but pricey

[1BADDLS1]

then i would go with cam that should be a good gain and not to much money.. if you install it yourself.. But you'd better know how or else..:nite:

bolt on car plus TR224 cam ='s low 12's high 11's :yup:

slp's H/C combos have proven :zzz:

[1BADDLS1]

That why their bolt on's.. bolt them in... you can bolt them off too... :thinkin:

you can swap out a cam in 3 hours too...

mods/aftermarket parts void warranties if found upon inspection and or reported as so by the repair facility

ofcoarse you can swap them out and not have a problem, but you have to be willing and able to... and not to forget

keep in mind all bolts ons dont take 15 minutes to swap out

i only have a lid and i havent bought anything else because i want to know everything about whatever i buy. i want the obvious next mod(exhaust) but then im thinking a torque arm and more suspension. h/c is definetely in the future but i want to get all the power to the ground and see what i can do with stock rear end and exhaust before crackin' her open. as i understand it from these forums, tuning is extremely crucial so i will have to save for that also.
suggestions would be amazing b/c ive recently gotten bitten by the scca bug. it seems like an f body could run with anything.

[jmhvenom]

Not to sure about the SCCA but imagine would take a lot. Exhaust you cant really go wrong with any of them, I would suggest for the price some Pacesetter headers, off road ypipe, and a cutout. That will give you the most free flowing exhaust for you money. Now, is it an M6 or A4? For SCCA you will need to throw a good amount of money into the Suspension.

[jmhvenom]

400hp w/ 4.11s should equal low 11s... Mid twelves with that setup is pathetic.

[Firebirdjones]

I believe Texas Speed is the company that currently has the fastest stock long block Fbody in the country with only a camshaft change,,,one of their majic sticks. That says a little something about them backing up what they sell. Larry.

it's a 6 speed. im not neglecting the straight line by any means bc i love drag racing but i love DRIVING also. i thought about 4:10s in the near future but im gonna stick with the 3:42s. how much does a cut out add, about 10hp? i want to pull hard through all gears (dont we all) but a cut out increases top end right? im undecided as to where im going with this project but i want a well rounded car nontheless.
keep the info coming!!!!:notworthy:

[Firebirdjones]

Ya that SLP setup is a little misleading though. That 400 HP rating from SLP is at the flywheel,,,not the rear wheels,,,so those claims are about right.
What SLP is doing is testing these components on a chassis dyno and then computing that to flywheel HP.
The 400 HP package is only headers, rockers, air lid, a diablo tune, cat back exhaust, and thats about it,,,so running 12's with so little isn't too terrible,,,I still wouldn't go this route though,,,there are better ways. Larry.

i heard that too and ive gotten alot of good feedback about texas speed products from people i run into around town. onw of my friends has the magic stick 3 ready to drop in his trans am. he has a y pipe with slp catback and 4:10 so im anxious to see how the cam will compliment everything else.

i read about that package in gmhtp and it doesnt seem like it is worth the amount of money. i'd rather buy a comlplete h/c package with rocker arms and rods for that amount of money.

[Firebirdjones]

Oh, by the way,,,all of the power pack SLP packages are based off of the LS6 intake as well,,,something to keep in mind. Larry.

[Firebirdjones]

Yes I totally agree,,,,I would rather go the head and cam route myself. If your going to make a change you may as well make a big one,,,right? :naughty: Larry.

[15T01Z28]

for easy installment slp works well. everything bolts right on. i have their coldair, air lid, headers+catback and the ultra Z hood. all of them were easy to install. the headers do hang way low as well as the y-pipe. however i did like the gains i got from these items. plus the sound is great. just dont try to go over any speed bumps! the prices are pretty high too. just know what you want your ride to do before you do anything to it.

[Firebirdjones]

Just so we compare apples to apples here,,,,I am curious who else offers tuned length headers like the SLP long tubes?

[secondgearscratch]

Oh, by the way,,,all of the power pack SLP packages are based off of the LS6 intake as well,,,something to keep in mind. Larry.

yes i heard that and thanks for reminding me. that further reinforces my point. if im going to swap my intake, ill go with the fast 90. it would be pointless to me to waste more money on a stock manifold that doesnt flow as well as the fast unit. but i dont know and thats the overall point so like i said keep it coming!!!!!:rl:

[WARP211]

400hp w/ 4.11s should equal low 11s... Mid twelves with that setup is pathetic.

That 400HP at the flyweel not the wheels.. its a bit pricy for the pkg anyway.. i would rather go with heads and a cam setup for that price..:firedevil:

I don't blame anyone for not ever using or recommending any of their products after an experience like that.

They lost my order and tried to cover it up by saying that my debit card was declined. I contacted Visa and got a statement from them saying SLP never attempted to bill me. I faxed it to them and made them eat their b/s. They never apologized for it though. On a second occasion they were completely unwilling to admit they shipped me a bent 10 spoke wheel and even after receiving pictures of the bent lip they then began to blame the shipping company for the bent wheel, which most likely didn't happen. They need to lose their arrogance IMO.

[Jerry01ss]

what other headers give the same power as the SLP ones they are very expensive and that is going to be my next mod...HELP ME PLEASE THANKS

took me 3 weeks to get part that was suppose to take 1 week. when i called they gave me this story about how they lost all there orders in the system had to redo everything...but would not express ship the part @ no charge made me wait 2 more weeks

Headers.
SLP. Design is flawed as they have serious clearance issues and are extremely curvy. Power claims on SLP's are simply bullshit. I didn't gain that kind of power with a cam install.
I went with Kooks. I needed a larger primary so I figured I would go with one of the best.
SLP vs. Kooks...
http://www.arbybean.com/ar/images/Swap013.JPG

Kooks are expensive though.
Pacesetter and JetHot seem to be great lower price alternatives.

I scraped my SLP headers all the time and I was at the stock ride height. Much more than I do now....and I am running the Kooks with a ProKit drop.

Catbacks
SLP. I like the Loudmouth under one condition. The rest of the exhaust is stock AND will stay that way. Meaning no longtubes.
My recommendations....
GMMG, Corsa, Borla are the pricey ones.
Magnaflow and Hooker are the ones I would go with personally.
Slowmasters catback sounds 'okay' but flows terrible in comparison.

MAF
SLP again banks on the rookie modder by claiming power gains. Which you will get. Because you will go lean. Sometimes lean enough to cause detonation leading to piston damage.
Stick with your stock MAF. Good for 500+ RWHP.

SLP Customer Service
I got a great deal on a new SLP oil pump for my 402 build. Took it.
Had an issue with the oil pickup bolt hole. The threads came out under nothing more than finger tightening.
Not in the mood to get into it about this again.
Read here if you would like (http://www.ls1tech.com/forums/showthread.php?t=390742)

Overall...SLP just sucks. They are using designs for the LS1 cars from 1998 while other shops are using new designs. Claiming bullshit power gains. Not backing their products.

Sure I missed something in there... :lol:
Any questions??

[02FASST]

Thanks Mr. Luos - great info.

Where did you get the Kooks? Did you install yourself? They look to have a MUCH cleaner and straight path! I am looking to do this mod in the spring and by myself - thoughts on install degree of difficulty?? What exhaust did you run with the Kooks?

Again, great info - thanks.

[Firebirdjones]

Still back to my original question that no one has touched on. SLP headers are tuned length,,,,who else makes a tuned length header? There has to be someone. Part of that price you are paying is for tuned length tubing which cost more to manufacture. I want to compare apples to apples as far as pricing goes.

Also 1bad LS1 posted TR TREX next to my post about the claim of texas speed having the fastest naturally asperated long block with just a camshaft,,,,what the heck is TR TREX and what does it mean. I can't make sense of all this abreviating. Larry.

[nhraformula]

That why their bolt on's.. bolt them in... you can bolt them off too... :thinkin:

you can do the same with all other ls1 compamies and thier parts cost less.

[02FASST]

Sorry Firebird - did not mean to hijack your post. IMOP the "tuned length" is marketing BS. Look at the kooks in the photo - which header do YOU think flows better????

It is not the one that is "tuned length" and bends around like a freakin' snake....

To your original Q - I don't know any other headers that are advertised as "tuned length". Anyone else know??

[Mr. Luos]

I got mine on special from a non-sponsor.

Installed them with the motor out of the car. The install is probably a weekend job for a first timer.

My set-up past that is cutouts and custom duals.
http://www.arbybean.com/ar/images/Exhaust-3.JPG

[Firebirdjones]

Don't worry about the hijack thing,,,we all get off subject,,quite frankly it doesn't bother me anyway.
I wasn't referring to which flow better,,,but it's been shown many times on engine dyno's that a tuned header will indeed make more power so long as the headers are designed properly.
The fact that the SLP tuned headers are very "snakey" I am sure is due to these Fbodies really not having enough room to do it any other way.
In a larger car with more room they could be designed much smoother.

In this instance of the F-body, with tight confines and no room to work,,,I really can see where these tuned headers from SLP can have adverse affects. I was just curious if anyone else made tuned headers for the LS1.
Most people were complaining about the price and comparing it to other headers that were not of similar design,,,which compares apples to oranges. I am just of the opinion that if a website like this is to be helpfull for everyone,,,,comparisons should be kept on a level playing field.

To be honest,,,the non tuned headers like kook headers, pacesetters, and the like,,,will all make about the same power on a given engine so long as tube diameters are the same. Just depends on how much money you want to spend, type of material used, coatings etc...
I will personally go with pacesetters for a couple of simple reasons,,,for one, headers generally will last me a lifetime because I don't drive the cars in inclement weather,,,and putting more expensive kook headers or some other expensive brand is not going to yield me anymore power, so the extra money that I saved can be used somewhere else.
I am all for top brand quality parts and I spend tons of money on other things,,but as far as standard style headers go for a street car,,,the pacesetters do just as well as the highdollar stuff, and seems to be the favorite among most F-body owners that I know or talk to. Usually I will spend more money on expensive headers if the fit is better on a given car,,(hooker super comps are my favorite on the old cars due to better fitment) but most everyone is pretty happy with pacesetter fitment and quality on these 4th gens it seems. Sorry, I am done babbling. Larry.

For deals...check out our sponsors.
Clearance issues?? No way. They tuck very nicely. I scraped my SLP headers often when I was at the stock ride height.
I am now dropped 1.5"-2" (ProKit) and I haven't scraped the Kooks once.

SO I SHOULD GET RID OF THE SLP MAF THAT CAME ON MY CAR I HAVE BEEN HEARING A BIT OF DETENATION. I HAVE THE MAF THE AIRBOX THE SMOOTH AIR BELLOWS AND THE CATBACK SLP EXHAUST (NOT THE LOUDMOUTH) THAT WAS ALL ON MY CAR WHEN I GOT IT. SHOULD I JUST PUT THE STOCK MAF BACK ON?

I've been hearing that too.. That the SLP Mass Air flow sensor will make your car detenate.. I live here in Cali and I never had any problems with the SLP MASS.. I have SLP cold air ind kit and mass.. Never had any problems with running lean or detenation problems.. :unhappy:

I bought my car from the original owner and he had custom ordered the car in 2001 with every SLP from the smooth bellows to the key fobs, Blistien Suspention, Dual Dual low restriction exhauset. The whole nine yards. This is my first Camaro and so far I have to say that I like what it has. But I really have nothing to compare to since this is my first Camaro. All in all I've been happy with the purchase.

You would need to get a wideband on it.


And GM wouldn't let a car get sold if there would be a problem. The SLP optioned cars are great. They are covered by GM's warrenty and aren't nearly an issue like their aftermarket parts support since GM covers it.
Just don't mod with SLP. :yup:

With the scanner i can drive my car and have my friend check out the A/F ratio... at idle and WOT... also when i'm at cruise.. i can look at numerous things map,iat,ect,tps,stft,ltft..... and list goes on... lol...

[Mr. Luos]

With a narrowband.
Which is just your stock O2's. Which may not show enough to tell you anything. Otherwise they would adjust and richen you up.

Wideband or bust on that one. :yup:
What scanner? HPT?

Naw man i'm talkin top of the line.. SNAP-ON or maybe a Genysis..

[Mr. Luos]

If it plugs into your ODBII port and reads the stock O2's...it isn't all that accurate.

Of course it will.. i've use them before to see when O2's are going bad.... it has about a couple sec. delay. and all the OBDII stuff isn't live right away anyway.. the only stuff thats real time data.. is CAN... and that will be in the new MARO'S.. it will be mandatory in 2008... all cars will have them..

[Mr. Luos]

It is the stock O2's themselves that aren't that accurate.
Not the ODBII system or the scanner.

[Jerry01ss]

Some do, some don't.

I bet you are running leaner than stock though.

so should i get rid of the SLP mass if im hearing it under a hard take off but its only there for a sec or two then it hauls ass but its only at the take off i thought i needed more fuel

[Mr. Luos]

That is when the motor fights the hardest.
It could be the MAF for sure.

so would i lose power if i went back to the stock mass or do you think i shoud keep the slp on there for more air flow? i know you said that the slp headers and y pipe were too expensive. what's a good alternative for the money and for the horsepower increase? should i keep the slp exhaust that's on my car it's not the loudmouth or should i get something else?

[Mr. Luos]

Keep the loudmouth for now. Wait until you hear it with headers to decide what to do about that.
Headers...go with Pacesetters or JetHots. Great pricing and they are good pieces.

I would personally remove that MAF. Might drop a couple (minimal) ponies, but it might be worth it if the detonation goes away.

sweet thanks i dont have the loudmouth i have the other one..so just get one of those headers do i need a certain type or just look it up for my car and when will i need to add more fuel??
thanks man

[Mr. Luos]

Headers can actually richen a car up a little.
Look for your year and you will be good to go.

do i want the long tube w/AIR or the shorty

[Mr. Luos]

Not the shorty.

Longtube with AIR if you still have emissions crap on it.

[02FASST]

Don't worry about the hijack thing,,,we all get off subject,,quite frankly it doesn't bother me anyway.
I wasn't referring to which flow better,,,but it's been shown many times on engine dyno's that a tuned header will indeed make more power so long as the headers are designed properly.
The fact that the SLP tuned headers are very "snakey" I am sure is due to these Fbodies really not having enough room to do it any other way.
In a larger car with more room they could be designed much smoother.

In this instance of the F-body, with tight confines and no room to work,,,I really can see where these tuned headers from SLP can have adverse affects. I was just curious if anyone else made tuned headers for the LS1.
Most people were complaining about the price and comparing it to other headers that were not of similar design,,,which compares apples to oranges. I am just of the opinion that if a website like this is to be helpfull for everyone,,,,comparisons should be kept on a level playing field.

To be honest,,,the non tuned headers like kook headers, pacesetters, and the like,,,will all make about the same power on a given engine so long as tube diameters are the same. Just depends on how much money you want to spend, type of material used, coatings etc...
I will personally go with pacesetters for a couple of simple reasons,,,for one, headers generally will last me a lifetime because I don't drive the cars in inclement weather,,,and putting more expensive kook headers or some other expensive brand is not going to yield me anymore power, so the extra money that I saved can be used somewhere else.
I am all for top brand quality parts and I spend tons of money on other things,,but as far as standard style headers go for a street car,,,the pacesetters do just as well as the highdollar stuff, and seems to be the favorite among most F-body owners that I know or talk to. Usually I will spend more money on expensive headers if the fit is better on a given car,,(hooker super comps are my favorite on the old cars due to better fitment) but most everyone is pretty happy with pacesetter fitment and quality on these 4th gens it seems. Sorry, I am done babbling. Larry.

Thanks for the added detail Firebird, I'm feelin' ya now on your goal to get a level playing field comparo. Gotcha.

As to your thoughts on pacesetter, you are spot on, no need to pay for the high dollar finish if you don't need it. I have had similar feedback on pacesetters.

Good luck.

ya i got to keet that shit so i can keep tags on it it has got to pass every two years it sucks.... and if i got some bigger injectors would that get rid of the noise and can i use the same fule pump????
THANKS...

[Mr. Luos]

Bigger injectors require a tune.
And they wouldn't help anyways.

The Mass Air Flow sensors read the amount of air into the motor. That can cause the lean condition. Replacing the injectors won't help the MAF read more accurately.

sweet thanks and thanks for the header info u saved me almost $400 i went with the JET-HOT with the off road Y-PIPE and they come coated!!!!!!!

[Mr. Luos]

Feel free to send some of that saved money my way. :lol:

Not a problem. Glad you asked around before just jumping in.

Glad I got rid of my AIR lol
