yea just like everyone else said, you dont need a chip for an exhaust, if u do get a chip it would be a lot better, and you better hope your not emissions checked on your inspection, you wont pass at all if you straight pipe it with no cat

2 bungs need welded to the pipe that repaces the cat. A spark plug non fouler (or2)is used in the rear bung hole ([8D]) to bring the rear 02 sensor out of the heavy flow of exhaust. Search on test pipes and youll get a better idea of what we mean.
