I just bought a 2006 RSX type-s, looking to buy just the muffler and i am wanting to get the Skunk2 Universal Muffler, which size do i get 3.0"/75mm or 2.25"/60mm ? thanks and sorry for the noob question.
Of course couldn't you feel it? Don't waste your money on custom piping if you're not going to shell out for mufflerswait, so have an intake+dcrh but im running on stock catback. did i gain any hp at all? and if i get a custom piping for my catback and still use the stock exhaust will my car gain hp or not? :bow:
