Since we're expressing our personal opinion, here's mine...it's also associated with personal experience. If you want a GREAT SOUNDING exhaust system, with many choices, and I'm sure there will be, even for the Camaro, than go with Corsa. I have a bunch of my corvette friends who all have Corsa's, even a couple with Borlas, but swear by the Corsa's.

Corsa offers a lot of veriations, from sound to performance, and they do it all without any 'drone'. Drone just kills the effect of any exhaust system, and you'll go deaf before your time.

I imagine its gonna be the usual manufacturers. Corsa will have the least drone and probably the quietest right there with the magnaflow. The GMPP is probably made by borla. I think the GMPP exhaust for the c6 is made by borla. The next step up will be Borla just slightly louder than the GMPP. The loudest will be the SLp of course or for those looking for the extreme, straight pipes or cutouts like on the 4th gen. I like it loud so I'll probably just drive down to the local muffler shop and have him cut the mufflers off and weld up some pipes. I did that with my c-6 and it sounds awesome. I've had straight pipes on just about every car I've had. Sounds good to me.. Oh, and for those that have never had a flowmaster, its like riding around with the muffler in your lap. The interior drone is terrible, plus they don't sound that good on ls1 motors, IMO. They sound good when you start them up and idle, but when you hit the higher rpm's it sound like its blowing air. It's like it loses its sound at higher rpms.

If a muffler is prone to drone, it will be in one specific small RPM range. Unfortunately, the RPM range is usually right at cruising speed in the top gear. And the drone is so obnoxious that you wind up cruising at a slightly different speed than you normally would (either higher or lower) just to avoid the drone. Corsas and Borlas both make high quality mufflers that do not drone in most applications. The Corsas generally cost more than the equivalent model Borlas.

I'm an exhaust aficionado, and I'd love to hear something from Fbodfather on how they're developing the exhaust for the Camaro. I know they are extremely limited by EPA noise emission standards, and although it hurts me to say this, if it even comes close to how good a Mustang GT sounds I'm all over it.

Catbacks? Usually none, unless the stealer can prove that your exhaust was contacting a piece of suspension, drivetrain, or body and caused the warranty issue.



Personally, I'll wait for Borla and Corsa to come out with their catbacks and choose one based on sound, weight, and drone. I'll honestly probably end up with the Corsa because they put a LOT of engineering into their systems to not drone.

Quick question. My dealer didnt know if GMPP shorty headers and catback exhaust would void the cars warranty. He said that it probably will. Does anyone know for sure?

Thanks,
Taz

they only void your warrenty for the exhaust manifolds and the exhaust itself. but they come with thier own warranty...if they are installed by the dealer.

I suspect GMPP performance accessories will be the same as FRPP parts, which do not void the warranty if installed by the dealer, but do void the warranty if you install them yourself or you pay someone other than the dealer to install them.

Ill wait till I hear from forum members hear that get theirs done. I had a Stillen Cat-back Exhaust on my Infiniti, the one thing I loved about the exhaust was that at Highway cruising I could get the exhaust coming out in just the right node (or anti-node) that caused a deep reverberating sound that I loved. So if a forum member mentions that sound effect, that will be the one I buy. Excelleration noise wont matter to much too me, b/c in that case all that I will be hearing is the wine of the Supercharger.

I'm hoping SLP comes out with a Loudmouth for the Camaro. I've always been a fan of SLP performance parts and the Loudmouths sounded great on the F-body's.

Depending on the look of the exhaust tips and the price, I'll choose either slp loudmouth or just muffler delete. The mustang bone stock does sound pretty good. The GTO actually sounded very nice bone stock. The mustang sounded really good with no muffler. My corvette scares the neighbors.

None. Stock exhausts these days tend to flow quite well. Deal with the other bottlenecks first if you're going for power. Long tubes, HFCs or straight pipes, and then catback. Granted sometimes, like with the GTOs, long tubes and catless midpipes sounded like shit with the stock catback so you pretty much had to get something done to the exhaust.

It is my knowledge...and experience...that a freer flowing exhaust most CERTAINLY will give a performance boost. Toss in headers, high flow cats (or none), and pure pipes and that exhaust will give a gain....pretty much over any stock exhaust. SLP Loudmouth and y-pipe. I had it. I used it. I saw the gain. Yes...there was a performance benefit.

There is no doubt in my mind that there will be a benefit from a chambered exhaust.
Wait.....hold on.....

I believe that the catback exhaust you would order is put on by the dealer to get around the federal requirement limts. Also I believe that having the the dealership install the exhaust system keeps from voiding the warrenty.

Sorry, but every speed equipment manufacturer is going to say "dyno proven" and what not. Even the Turbonator. I'm just saying that I know a lot of stock catback cars that make big power, most of which being LSx cars. It makes little sense to put a freer flowing catback behind stock cats because the exhaust will only flow as well as the tightest bottleneck, which they are.

More catbacks are disproven than proven on third party dynos.


Granted, I'm talking modern technology. The 4th Gen F-body exhaust was designed 16 years ago, and modified slightly 10 years ago.

My desired set-up:

1. Kooks LT headers w/catted x-pipe
2. Corsa cat-back or axle back.
