O0ok well I bought a catback exhaust system with headers from ebay.. (yeah I no I shouldn't of but f**k it)..I've had it for over a year n I just don't like the way it sound.. n I recently put a skunk2 test pipe and still sounds bad.. so I was told to by a name brand muffler and just throw it in n it would sound better is that true or do I need to change the whole thing??
