Wide F...ing open long tubes!

[johuckabee]

I want to do a long tube setup w/out cats that dumps the exhaust on either side of the car using two custom sections of pipe bolted up to the collectors. This is not a post about exhaust sound or raspyness so don't come in hear starting s..t about it sounding terrible. I like an exhaust note that is wide open loud and raw. I have a loud mouth right now and like it but i want people calling the cops when i drive by because the sound is breaking their windows. I am talking really offensive. What problems do you think i would have making this work?

[tabasco]

what other mods do you have?

[johuckabee]

cold air, k&n, lid, ported MAF, bellow. I am planning to replace the intake and TB and cam the engine as soon as i have the time.

[bww3588]

your main problem will be burnt valves.

[The Rookie]

Besides tickets???

[oneBADDz]

Seriously, just run it through the loudmouth with the headers and no cats, it's stupid loud, I know I've got it. From 50 feet away it hurts your ears. I've got a video but it doesn't do justice to how stupidly loud it is, I tried to do some drive offs and drive-bys and get it on here but it seems like the camera just doesn't let you know how loud it is regardlesss. It sound effin GOOOD and pisses people off constantly. I think ground clearance is going to kill you out the sides unless you go at least back a little farther and exit in front of the rear tires. I also hear you'll never be able to put on subframe connectors either. Just imagine loudmouth x6 or so, totally unrefined raw sound. I love it. I never get tired of pissing people off with it, never

[johuckabee]

burn valves? tickets? how about you actually contribute instead of making smart ass coments. Not you z_driver1, you're chill. I want to know if anyone has done it and if so how did they made it happen. I want to do it because it would be unique.

are you fuckign kidding me? you ask what problems will be involved and you take burnt vavles to be a smart ass comment? go ahead and run open headers and see what happens. youll end up with burnt valves if you run it open all the time. keep being an asshole and see how much help you get around here.

[oneBADDz]

There are pics on here or LS1tech, I'll see if I can find them. Some chick ran it back a few feet and straight over in front of the rear tires

The h pipe will give more of the sound you want, while the x will benefit a little more in power due to better scavenging, but it cleans up the sound. I hope you do plan to put one of the two in it?

[TwistedSS]

thats awesome...lol it will be loud as piss!

[jmhvenom]

im planning on running dual cutouts on my Y pipe when i get my headers installed, will have the stock exhaust running out the back if i need to be silent... probable will also keep the cutout i have on the I-Pipe right now so I can have some kind of inbetween

[hammertime]

Well, considering the exhaust pictured has converters, a crossover and the chambered mufflers, that might not be so incredibly loud.

A crossover of either kind will smooth out the sound by connecting both banks of the engine. If the pipes are long enough to reach in front of the rear wheels, you shouldn't have any problems burning valves I wouldn't think.

But yeah, if you have as open header exhaust breathing out the side of the car, I would expect tickets to be a problem too. I knew a guy that had a pinto with a 302 and headers, and the guy that built it had put 1-chambers and glasspacks on each side. He still got loud muffler tickets after explaining to the cops he had four mufflers.

I just posted pics of the only one I knew of that had done it, not to be specific. I don't think he wants to run em that far, but I think the same setup without cats would get exactly what he wanted so I thought the pics might be of some value

[Mr. Luos]

Check sig for wide open headers clip.

It was the most annoying thing to drive EVER.
True duals dumped before the axles. Loud..good power.

[spazzyfry123]

Burnt valves? Can anyone explain this to me? I don't understand how running a short exhaust system (meaning only right after the header) would cause the valves to burn. What specifically causes this?

The video in your signature...Is that of headers only? Or is it running through mufflers as well?

Also, what are the spec's on your cam?

[Mr. Luos]

Headers only.
226/234 554/575 112

[johuckabee]

where are the nearest exhaust hangers after the manifold. i could get under my car and look but i would rather as you. because if i were to go with side pipes, i would want to have a hanger on each side just so all of the weight would not be held up by the headers.

Sounds great:Popcorn:

[WS6TNT2K2]

My exhaust doesnt dump before the axle but with dual 2.5" straight pipes no cats or muffs it rattles the neighbors cookie jars. It is VERY loud but if your not a puss youll enjoy the smooth sound of screaming exhaust. I can't wait to upgrade to the 3" straight pipe sitting in my garage for a deeper sound.

[Mr. Luos]

Sounds great:Popcorn:
Eh...

New clip sounds better with true duals.

[WS6TNT2K2]

That is exactly how my car sounds. Sweet video man. What size pipe are you running?

[Mr. Luos]

3" duals. Non mandrel in order to fit with torque arm.
4" X-pipe.

A very custom set-up.
What mods are done to yours?

[WS6TNT2K2]

So far I have a Whisper lid punched the screen out of the maf, 160 stat headers and a predator that I had to send back for a tune. When the weather gets a little more stable around here I am putting the 3" pipes on.

[Mr. Luos]

Good start!!

Probably doesn't sound the same at idle though eh? :lol:

[WS6TNT2K2]

After watching the Vid I would have swore that was my car except I have an 02 WS6 the 3" is a little deeper I definetly like the sound better. 2.5" is a little raspy and crackles a bit but nothing to bad. PPL love the way the car sounds. What is your set-up?

[Mr. Luos]

TSP 402
248/254 629/622 113 TSP cam
Stage III LS6 heads
Kooks 1 3/4 longtubes
3" duals


You probably get the idea. :lol:

[WS6TNT2K2]

That is quiet a set-up. What Hp range are you pushing? I bet you turn some heads. I like to think I am a rolling rumble symphony giving everyone in ear shot a taste of good music.

[Mr. Luos]

Haven't gotten a complete tune on her yet. Only about 75 miles on the motor actually.
Looking for roughly 500 RWHP.

[WS6TNT2K2]

Good luck 500 is a strong number but easily done these motors have an endless amount of potential. It comes down to how much $$ you wanna lay down. I have kind of taken an interest in the new STS kits out there but I am very much an natural aspiration kind of guy.

[Mr. Luos]

That is basicly my goal.
If I can see 500 RWHP off a fairly streetable car...I will be happy.
Of course...mine is N/A.

[WS6TNT2K2]

My main goal for now is to not over power the stock driveline and start breaking things (rearend tranny clutch) you know. But at the same time I want to have a damn good time with my car. I wish I didnt have so many projects that way I could dedicate all my time and money to the TA but thats life.

[Hotrod]

your main problem will be burnt valves.


I hope I don't get called a "smart-ass" too but I agree! I've been told by several mechanics that this is exactly what will happen. I know you wanna be unique but it ain't gonna be unique sitting in the shop with burnt up valves!

[TARZAN]

Do a full exhaust with a cutout

-Will

[Mr. Luos]

Open headers won't burn your valves.
No pipes off the heads would.

[jimbo98z]

There really aren't exhaust hangers until fairly far back in the car. The first one I can think of is the bracket that holds the Y-pipe up on the passenger side towards the back. You could weld in new hangers without any problems, if you put them in the right place.

I have pacesetter long tubes running through a flowmaster with a cutout in the Y-pipe. Honestly, with the cutout open, it sounds almost the same as when I started it with open headers. It may be a tiny bit quieter or less raspy, but not much. The good thing about the electric cutout is that I can close it and make the car fairly quiet when I want to.

[Huskerz1]

I'm with this guy. Doesn't the LS1 require some kind of back pressure?

[bww3588]

if you run them for a long period of time they will eventully burn. i got a 327 sitting in my garage with burnt vavles because we ran open headers because we were too cheap to put an exhaust on the Nova. we put about 5k miles on it and they burnt.

[Mr. Luos]

Headers for the LS1 come with a collector.
Should be enough to prevent air from making it to the heads.

yeah i know. the way i always thought it happened was when you rev it and let off it sucks a little back in......idk man....chances are slim but i wouldnt want to risk it. IMO

[Mr. Luos]

Longtube headers should be more than long enough to prevent that from happening.

I do agree though. I didn't drive mine long open headers and wouldn't do it again.

[bww3588]

true that, and the way i see it, your just asking for a fix-it-ticket.

[Mr. Luos]

HEHE...

Had to cut my duals off right before the axle. Nothing but pipe and an X. Needed to get my tank down.

Magnaflows are getting hung up tomorrow!

[johuckabee]

Love the way that sounds. How does the much longer exh. duration vs. int. duration on that cam effect your setup?

[Mr. Luos]

I get pretty bad surge down low. Well...not terrible I guess. Probably just needs some more work on the tune.
Not a huge torque cam, but it does okay.
In order to run a cam like this, you need to give it air. I think I peaked running the heads I am running at 530 RWHP at 6600 RPM.

[johuckabee]

What do you think that your next move will be reguarding cylinder heads? Also, I am thinking of going with QTP long tubes with the high velocity collectors, what do you think of these?

[Mr. Luos]

We are thinking two different things.

Cylinder head wise...I will probably go with something that dumps my compression because I will be boosting the car.

My longtube headers won't be getting changed anytime soon. Kooks 1 7/8" longtubes.

[johuckabee]

I'm not trying to sell you QTPs or anything. Just asking for opinions of them. They look like they would produce awsome scavenging well into the secondary piping.
