Anyone out there know where i can find a backbox with twin tail pipes for my car? id like something that has a nice exhaust note without making me look an idiot and looks original for my car, something like what came on a sport would be good, possibly a lil larger but not so big it requires any modding to my rear mtec2 bumper. Any help would be fab, thanks

eurocarparts worked for me but i managed to get a straight through exhaust with twin pipes and a custom built manufold for 600 quid which gave me like 8 bhp great or try gsfcarparts.com
