Ok heres my dilemma. I work for a GM dealership and can get the GMPP sport exhaust for my 2.2L for $376 bucks (free shipping because they ship it to the parts dept), also, which one has a bigger diameter so when I go turbo in the future I dont have to worry about losing too much power until I can get a 3" exhaust bent up. Im not sure if I can order a corsa exhaust through parts anymore, but I was wondering if anyone can give me a suggestion on what they would go with:

Get the GMPP for $376 (no tax, no shipping)

OR

Save up some $$ and get the Corsa Touring


Also, which one will show more noticeable gains. Im so confused,lol.

mikekoz

i don't know about the gains.. but i have GMPP and i love the sound.

Corsa Sports shows the most gains! That Y i had got it. But between them 2... I donno about gains? I would go Corsa Sport for the Full HP! Good Luck either way tho

I believe both systems are 2 1/4 diameter. Pacesetter is the only cat-back that's bigger at 2 1/2 in

GMPP!!!!! Sounds better. Both systems are 2.5".

we need audio clips to compare the two systems, quick!

I thought the GMPP was made by Corsa!

WSFrazier

Do you not know what GMPP stands for? lol

g5mike

Gmmp is made by Borla and I love it, the sound is awsome

GMPP is made by borla... and why dont you guys serch the exhaust threds... there are sound clips, videos, and specs for almost all of the current cat-back's

.... GMPP= G.M. Preformance Parts

WSFrazier

There is a huge thread with sound clips of every exhaust out ATM.

red_wing_2121

Yes, I know what GMPP stands for. I also knew that it wasn't actually made by GM. I thought I heard it was made by Corsa which would have defeated the purpose of this thread. I was wrong about the manufacturer, oh well.

can we get some dyno's on the 2.2?

Stealth06LT

Whats the diameter of the GMPP? I know the Corsa is 2.5".

WSFrazier

Both are 2.5". Pretty much every exhaust for our cars are 2.5" except for the Vibrant and DZOD (or w/e they are called).

specvgini

can you guys post dyno info on the 2.2 .

GMPP is 2.25 for the CSS/SC. not sure why for a 2.2 it would be bigger.

Asphalt Assault

okay for the SS/SC based on previous posts I have read.

GMPP is 2.25"
Magnaflow is 2.5"
Corsa is 3.0"

maybe more research needs to be done here but that is what is known to me.

WSFrazier

TurboTech lists the corsa as a 2.5". Corsa doesnt seem to list it on their site.

Stealth06LT

i think im leaning towards GMPP because GM wont void my lease if I install it (im buying it off lease in a couple years anyways)

Vette Jr.

Corsa isn't 3" it's 2.5"....... you need to do more research

Well I did say that didnt I. I also said I was going by what I know from what others said on the forums. If I was in the market for exhaust trust me I would know. SO since I am not in the market I dont need to research it yet. I think you need to get rid of the chip on your shoulder.

Asphalt Assault

void your lease? you got to be joking. I am leasing and I have sold the wing, head lights and I am getting GM stage 2. yeah I plan on keeping it but they are not going to run me down and say "you modified your car, your lease is now void"? relax. decide if your keeping the car and then make the decision to modify or not.
