This weekend I plan on getting 3in exhaust pipe from cat back with a fart can stickin out the rear of my 09 AVEO5... that involves cutting out a resonater (silencer type thingy) and the stock muffler of course.

My question: Will this void my warranty? what are the restrictions and limitations on aftermarket exhaust? I really REALLY do not wanna void my warranty but you know i still wanna have fun.
