Well guys im thinkin about having my y-pipe changed out for somthing a lil better than stock and this is where the questions start. I have a borla muffler that is si 3in and dual 2 1/4 out and was curious if there would be any beniffit to having the the stock y-pipe cut off; then dual 2 1/4's ran back to the muffler and then a single 3 dump. The muffler is a straight through design so I didnt think there would be any problems if I just turned it around. Would there be any gains from this vs just replacing the stock y-pipe with a better flowing y-pipe??
