Im looking for a good sounding exhaust set up.. I want to do bassani mufflers but i have a question.. Would it be better to do a y-pipe to one single muffler or an x-pipe to 2 mufflers..? Also is it better to do 2.5 inch midpipe and 3 inch back or to go with full 3 inch all the way back..? Which would be best for sound and what would be better for performance..? The sooner i can figure this out the sooner i can get my exhaust.. PLEASE HELP
