exhaust question?
i got a friend who is installing either a cat-back exhaust or a high performance muffler. i always, for what ever reason, thought cat-back meant that the customer would get a new catalytic converter, the pipe, and the muffler. if you only get some pipe and a muffler, how could this really be that much more efficient than just a muffler. surely the pipes could not be that inefficient? anyone with some insight on this?
