Ok guy/girls...our long awaited car is almost here. I like many others cannot leave well enough alone when it comes to my cars. One of the first changes to my 2SS will be a mean sounding set of mufflers. I have always been a Flowmaster fan, but want something different this time around. I have narrowed it down to Corsa, with the aggressive black mufflers, or SLP loudmouth set up. I like loud muscle cars. Does anyone have any thoughts on these 2 systems, experiences, feedback, other suggestions.

 

its a new exhaust configuration on a car thats not out yet, i dont think you will find any info yet on which companies are developing what, what their exhausts will look like or sound like.

 

I have a Corsa system on my current Camaro. I would have to be very impressed by some other system in order to choose anything but that for a 2010, assuming they make one.

 

borla has designed the gmpp system for the camaro so im sure they are and will be the first to have a system out for the camaro.
i plan on doing the borla catback system and probably hooker long tube headers. just to give it that deep aggressive sound.

 

1. The car is still 3 months from ending up in the showroom.

2. You haven't heard the Camaro's exhaust yet.

3. You have no idea on how efficient the Camaro's exhaust is.


One of the hot rodding mags got ahold of a Challenger SRT8, and (like you) the first thing they did was install an aftermarket exhaust.

Funny thing.

The aftermarket exhaust was more restrictive than the one from the factory. Turns out, the aftermarket exhaust had a smaller diameter than the aftermarket one. If I remember, I've also read that the Challenger SRT8's mufflers are perhaps better than any available aftermarket item.

Both cases, it was Borla.


Wait till it's actually in showrooms and you've heard the exhause tone yourself and read about how efficient it is (or isn't) before blowing that hard earned money that might have better use elsewhere in the car.

 

well obviously they have done the research on the gmpp exhaust and im sure it has a better sound to it( better as in deeper, and maybe a bit more hp rating). and it was already confirmed from a guy at borla that they made the gmpp exhaust. i would imagine if borla made this gmpp exhaust then it has to have some advantages over the stock.

 

I'll be installing a set of chambered mufflers on my car. I love the way they sound.

 

That magazine was Hot Rod. The Borla Magnum system they installed had a 2 1/2-inch diameter, compared to the stock system's 2 3/4-inches. The Borla system, however, picked up 17 HP on the dyno over the stock system.

 

I promise that welding a set up Dynomax or equivilent bullet mufflers will outflow, make the car louder, and be cost effecient. May not be everyones cup of tea however. If GM runs a 2.5 inch true dual system stock you will have enough pipe to support 500 hp or so.

 

i think im going to go with 3" all the way from the headers.

 

Muffler? What muffler? I plan on getting rid of mine probably the first week. It should be loud enough then... Anybody thought about doing the cutouts like we use to?

 

Why? From what I understand, bigger diameter doesn't necessarily make more horsepower or torque.

 

3" good idea-she'll breathe easier for the future mods

 

But until you add the required mods, you'll be down on torque numbers due to the huge 3" dual exhaust on the factory setup.

I would stick to either a muffler sawp/muffler delete until the new mods are done. Heads/Cam, cold air, and a set of long tubes would get you close to actually using the dual 3" exhaust, but ideally, yoiu would be looking at stoker or forced induction to need that kind of exhaust flow. If the cats are as efficient as the ones on the new Vettes, then you won't gain tons of power form cutting them, just more noise.

 

3" is a good diameter for a single I-pipe, but oversized for a true dual exhaust unless your pushing serious horsepower. As mentioned above, you'll be less efficient with a system that large without a serious head/cam or power adder (ie. s/s, nitrous, turbo).
