Best performanc exhaust?

[tajoe]

Let's put the sound question aside for this one. What is the best performance exhaust system on the market for an LS1? I've heard Borla, Pypes, Magnaflow and Flowmaster. Any thoughts?

[Mr. Luos]

Flowmaster is at the bottom performance wise.

Past that, it really depends on the sound.
I personally like Magnaflow and the GMMG.

[nhraformula]

hooker. great price, free flowing and not alot of money

[Vertiviper]

"no" exhaust,..he he

[MarkuzLS1]

I like my Corsa. Gained 17rwhp with it and an SLP air-lid.

[The Rookie]

I love my MagnaFlow

[SSwt00SS]

i love my Loudmouth...:notworthy:

[jeffsredt/a]

I love my Borla

[third_shift|studios]

this is a question for the car gods...

[knewsock]

I have full out slp exhaust and it's simply magic. and the women hate riding in it now. ha ha

[BLKbandit98]

It is argueably the loudest and best flowing cat back on the market till date. Hence the name "LOUDmouth,":lol: it doesnt have a muffler for gods sake. Going up a hill in 4th at 2K rpm is unbearably loud. I had to scream to my friend and couldnt listen to the radio. But around town its fine as long as u dont push it. Get ready for complaints and gettign pulled over like i did. (but no tickets, had nothing to charge me with) but from outside IT IS LOOOUUUDDD. I had my rev his car up to just 2.5K and it sounded like a nascar.

loudest thing out there is a cut out.

[BLKbandit98]

i know, bu he said "exhaust"

[tajoe]

I like my Corsa. Gained 17rwhp with it and an SLP air-lid.
The air lid is a must. I want the right exhaust to go with it. Never heard of corsa. Affordable?

I pray to them but they won't answer! LOL:worship:

Would you consider $800 affordable? If so then I guess they are. lol

Magnaflow cats and Muffler here, it has great sound while not being to loud, but when I get on it, it make some noise.

[2001somws6]

i know someone with bassani. I heard it and i like it. also saw there booth at the power tour and they gave me a bunch of flyers. Im sure im going with that set up with headers.:burnout:

[00redws6]

i like my hooker cb

[rezor]

just got the slp kloudmouth yesterday and i love it sounds great and made quite a difference

[Mr. Luos]

The Loudmouth was basicly my first mod.

It is long gone now though. Sounds great with stock manifolds. Add headers and add a ton of rasp and it just gets too loud.
That is why I recommend the Magnaflow catback for most cars. Fairly tame at idle, sounds great when on it though. Sounds good with headers and beyond.

[jd2002ss]

Kooks+GMMG =:yup:

[The Scientist]

Hey jd2002ss or anyone else with this setup,
I have a question about the kook/gmmg setup. What is the interior sound of that setup while cruising at interstate speed? I just put kooks on with ory pipe and need to change my old flowmaster cb. Any idea if the interior resonance will be as bad as with the flowmaster?

[BLKbandit98]

Kooks+GMMG =:yup:


Thats the most expensive setup. $700 for the exhaust and about $1100 for the headers and y pipe. Plus the $500 at least to put them on. Over all its around $2200-2300 for just exhaust. I dont think thats worth it. Sure itll sound bad ass, but is it really worth $2200. Just think if u spent it on other things what kinda power ud get.

[Danger731]

What ? WHAT ? , I can't hear you !

[The Scientist]

You have to pay to play and some like to have high quality in their performace parts. Lets look at the cheap-to-modest priced set-up.
$400 for the exhaust (SLP), $700 for the headers (may come with an ory) plus $500 for the install equals $1700. Either way it is a lot of money and yeah you could list all the mods you could get with the $500 difference but what good is it if you don't like what you got?

[Danger731]

stainless steel = stainless steel, lol or oh thats right - stainless steel = stainless steel

LM install - free , muffler shop to tack weld the joints - 20 bucks.

Just don't get " blowmaster"

must've been me al. here's a dyno of the wife's car when i swapped from the borla 3" single adjustable catback to the bassani tru-duals

[caseyWS6]

i love the sound of my borla:notworthy:

[Banshee]

I just bought an SLP Loudmouth Exhaust with the additional Loudmouth 2 Muffler for those times I'm out with my wife and she actually wants to have a conversation with me. But, 95% of the time, I'm running the Loudmouth!

[krummrey07]

:burnout: I love my corsa and their tips r very nice!!

[The Scientist]

Having just installed Corsa on a kooks-ory setup, I find that it pops way too much especially around 3000 rpms at 1/3 to 1/2 throttle. It is the same unrefined sound that I hated so much with open cutouts when not at full throttle. I suppose some would call that "raw" sounding. I am happy with it, just not what I was expecting.

[tajoe]

Anybody running Dynomax Bullet? If so, how do you like them?

[senicalj4579]

in my opinion considering price,performance,material,and sound,you cant beat the magnaflow

[my1973form]

SLP used the Powerflow muffler on both the Firehawk and the opted SS Cammaro, it was the best flowing muffler aside the noise level was the only muffler the passed EPA noise level.

[scooley]

Borla.
I get tons of comments on the sound plus it runs great.

[sootymethod]

Out of all these comments only 1 for GMMG? I am sure everyone has a taste for their own exhaust system....
I myself have GMMG system and it was costly but well worth it.I did a lot of researching on exhaust systems and I only wanted the best and I believe that to be GMMG. The only drawback that I see are the polished tips but the system itself will gain you horsepower if accompanied with a free flow lid....good luck to ya..

[Corona-Extra]

another one with borla

[98ramairguy]

I have a loudmouth, I like its loud, sounds great and gained some power

[whiterock1]

The Loudmouth has no restriction--only a resonator that is little more than a widening of the pipe. How can anything else have less back pressure and therefor pass more horsepower through? It is a matter of physics. While you can make the argument that lowend torque may suffer a bit, high rpm power is where the hp shows it's peak, and the less restriction the higher its peak will be. (btw, Street Legal means 'street legal.' In all 50 states with respect to noise.)

[BLKbandit98]

It terms of performance i think the Loudmouth cant be beat. Its the best flowing for f-bodys, or thats what every1 says. But with LT's and ORY watch out. It is DAM loud, and just gets louder and louder once a cam is added.

If you have never seen the inside of a corsa muffler you may not understand, but the corsa is in essence a straight pipe that splits with three slits that release sound waves. It might flow more than SLP (not by much), not sure because I have never seen the flow numbers.
