will this system do much for my camaro. i already have a flowmaster muffler. i'm thinking maybe with these headers and y pipe and then maybe a high flow cat i'd notice a decent improvement.

to be honest, exhaust wont make much of a difference in power, just sound, it doesn help the engin breathe, but its not a noticeable horsepower gain. exhaust is a good supporting mod, not a performance mod, you add things like heads, cam, or forced induction and exhaust helps out tremendously. on a stock engine, it just makes it sound better and run a little better
