I am in need of a 4 into 1 exhaust for my 1975 CB550 four. Right now I am running a 4 into 2 Megaphone system, that just got me my first ticket in 20 years. I'll confess, it does sound like King Kong farting in a cave, however, after hearing some of the Harley guys bikes, I didnt think they were still concerned about useless noise. Anyone got anything ? complete system, headers or anything that could be made into something runnable?? As cheap as possible ??
