The aftermarket mufflers will improve flow and the longer they are, the quieter they tend to be if you are worried about noise.

Good to know. Since the general census is not to expect and performance or mileage gains with a high flow muffler, I was curious if changing cats and the y pipe only could produce any gains and could cost about the same money.
