Does a free flow muffler provide a significant horse power improvement over stock? What if i get a wsp y-pipe and catback system and a quiet muffler; would that make any sense? would the gain from the y and catback be nullified?
TIA

Muffler will add....
no noticeable gains...best bets are to upgrade to a Y-pipe, hi-flow cat and 2.5" ctaback. as for the muffler IMO, it is not that necessary to change since it isn't THAT restrictive and having a little back pressure doesn't always hurt that much either I guess.
