OK, well im on the market for a cat-back and im trying to keep the noise level to a minimum, I dont mind if the thing makes some noise at 3k rpm+ but im not trying to attract attention here.. Currently im thinking of getting the apex-i, so any suggestions would be great

 

if i remember correctly, catbacks refer to b-pipe and muffler so why don't u just change your b-pipe to get rid of cats and keep your stock muffler?
