Well, I am getting my Cobalt SS/SC pretty soon, and i have a list of mods ive been thinking about... So, Here it goes... GM Stage 2 kit, GMPP exhaust and headers (for warranty sake) and possibly an injen cai. if anyone has these mods, tell me how they are working out for you, and if u have any dyno results, please fill me in on power gains. thanx!:twothumbs

GMPP doesnt sell a header for our cars, its just a ported manifold from what i understand, and it doesnt do much.... buy an aftermarket, it wont void your warranty...

woops, yea thats what i meant, i just said headers cuz thats the first thing that came to my mind when i thought of an exhaust manifold. my bad, lol. and btw... should i risk the chance with the intense stage 3 kit?

i wouldnt just go with the stage 2 and get a smaller pulley. I plan on getting the hp tuners software or find someone with it to tune my car for hte pulley.

You should really do some researching around the site, go through the sections and search, looks as if you have alot to learn.

ive got gmpp exhaust and i enjoy it. it sounds extremely nice and isnt rediculously loud until you get all over it. check out the official exhaust thread to hear what it sounds like.
