Do cat-back exhaust systems improve performance?
A cat-back exhaust increases performance by upgrading a stock exhaust with a large-diameter and more efficient mid-pipe, muffler, and tailpipe. Since the catalytic convertors remain, emissions are not changed. However, vehicles will have an improved exhaust note, better fuel mileage, and weight reduction. via
