i want to get a GM stage 2 and new exhaust. i have noticed that the corsa exhaust system seems to be the favorite. I found them here http://www.gmpartsdirect.com/results.cfm?singlepart=1&AddPartNumber=14128&partnumber=14128 on gmpartsdirect.com. can i have the dealership install it and not void my warranty since GM sells them as one of thier products like the stage 2? any clue as to install costs on the exhaust?

usually an exhaust wil not void your warranty.

what exhaust do you have/recommend iso?

corsa is one of the only fully GM backed exhausts. corsa will in no way with no questions void your warranty, that is a benefit of them. normally no exhuasts will, but say it plugs up and messes your engine up, they will blame the exhaust and void your warranty. but not corsa, your straight with them :) im an authorized corsa dealer, let me know your best quoted price and i bet i can beat it!

what exhaust do you have/recommend iso?

i don't have an exhaust yet. i bought a magnaflow 2.5 inch inlet/outlet muffler and i plan on having muflex mandrel bend me some 2.5 inch piping mated to the stock cat and the new muffler. what can i say? i'm cheap.

What are the benefits of the Corsa Exhaust in comparison to the GMPP exhaust? I'm looking at going from header to tip.

Since it is fully backed by GM, will they install the system for you at the dealership? And what is your normal price for the sport exhaust?
