had my exhaust on for about two years now, but its not really that loud as its just the backbox ive replaced... (i dont like really noisy exhausts) but i fancy having it a little bit louder as its not very loud at all... and i was considering cutting out the crappy centre box on the standard exhaust system, (it catches on bumps anyway!) i have some exhaust piping that is the perfect size but i dont want it being raspy... i dont wanna do it and then not like it you get me? ive still got the cat in place, so i guess my question to the n/a members is does it get raspy without the centrebox? o
