I know the subject of which exhaust has been discussed many times but I am specifically after just a backbox for my cup which is single round and at least 3.5 inches in diameter. I know Magnex seems to be a favourite for people and I would like a Magnex but although they do the exhaust style I want not for the Cup\172 Sport which is a little dossapointing for me personally.
Can anyone advise and recommend another one in this style. Comments on loudness and any other details would be great. Pictures if possible would be spot on.
Thanks in advance,
Chris
