if i'm not mistaken many people on this forum have told me that the 2.0 ss and the 2.4 ss come with the same exhaust from the factory? if this is the case wouldn't these gmpp exhausts fit the 2.4 as well?

 

i believe these exhausts fit all of the 2.2, 2.0, and the 2.4

 

it should fit both.

 

ok thanks guys! so far I like the sound of the gmpp performance exhaust the best but i have yet to hear a borla...also does anyone know if flowmaster is or has made an exhaust for our cars?

 

i agree i like the sound of the gmpp performance exhaust a lot. But i'm not sure if I should go with the touring verison or the performance one. Does anyone know if the Perfromance exhaust will be able to pass inspection on my car in New York?

 

I'd go with the performane and I have no clue about the inspection thnig, but I don't see why not.

 

is the performance exhaust really loud inside of the car? i don't want to not hear my music becuase of my exhaust.

 

i didnt have the magnaflow cat back, but a custom axle back and it had some farts during decel .... but its sounds mean as hell espically during decel ..... ive been told all the time that it sounds like a mini v8 ....... nothing but grrrrrrrrrrr

 

anyone know of a good site to look at for performance parts

 

ebay has been showing more and more parts but look in the vendor section for more ...........

 

out of all the exhaust i have to say taht corsa sounded the best and thats why i am going with it. It will be here on friday and by sat night hopefully i can have up some videos. any locals wanna see it PM me sat night would be good or sunday day would be kool. as for the gmpp cobalt addiction is a sponsor do an ebay search for cobalt addiction and they have the GMPP for a really cheap price. Better than parts direct.

 

not to jack this thread, but which exhaust is best for gains? which corsa exhaust are you referring to above for sound (sport or touring)?

 

I believe corsa has the best gains 12hp/8tq thats the sport exhaust but for the love of god leve your cat on.

 

haha i wouldnt be taking the cat off for sure, but just out of curiosity, why dont i want to remove it?

 

someone please dyno the GMMP performance exhaust lol

 

1. emissions, biggest reason.
2. Sounds terrible (no offense to peeps with no cat)

Those are my reasons.

 

has anyone heard the touring exhaust yet? is just slightly louder than stock exhaust?

 

would that be why it gets so high pitched in that clip previously posted?

 

to be honest, I am not sure. The label says 90dB, not sure what New York laws are.

I'll try to do it this week, by saturday. oh, btw...I need $75 j/k

I'll say this once more, the packing slip had the diagram and it says 2.0 and 2.2, nothing about the 2.4. You take your own risk with that one.

I have the performance exhaust, I believe that the touring is louder....I saw the info somewhere, I just cannot find it right now.
I hope this answers some ???'s
I posted 2 clips on the 'official exhaust thread' of the exhaust in action

 

from what I understand yes, the cat has a large effect of the sound, but also there are other modifcation done to said car, so the cat can't be blamed squarely.

 

My 3" duals do nothing but low deep growl. Not even near mid or treble sounding at all.

 

would you take a pic of the last part of the exhaust, under the trunk....I'm curious how its run....thanks

 

did you notice a hp gain? obviously you have a custom exhaust, or am i wrong

 

I have the GMPP performance exhaust. I notice a pick up in the mid to upper range. A buddy has it also and when I was stock, we raced. We were side by side until I hit 4th...he pulled a bit. I noticed it even more when I went into 5th, he walked away, like I was standing still. Now we are real close, unless I screw up the launch which I like to do...

 

holy crap that is ricey, talk about rasp!
