exaust

i have upgraded my 1995 acura integra with a k & n cold air intake kit and a new flowmaster exaust muffler. the shop i bought it from told me that flowmaster had tested the muffler and that running new pipe from the muffler to the header would not help out with additional preformance. is that true or would bypassing the cat help me out with preformance and flow?

Leave your cat in place. Get a cat-back exhaust if you want bigger piping but you won't see that much of a gain. You'll probably lose some low-end torque as well.
