Hey i finally decided on a new exhaust. A muzzy full system. One of my partners bought one put 400 miles on his busa and decided to go turbo. so he' sold me the muzzy for $350. I'm thinking thats a good deal. Now the question is do i need to do an airbox mod to get the most out of it? Haven't got the power commander yet, most likely will get one in the next week or so. the pipes being put on tomorrow so i'll let you know what i think after that. By the way anyboday done in mods on a muzzy exhaust to get more power or a better sound?
