CB550 exhaust system
« on: September 08, 2008, 10:22:33 PM »
So, I'm ready to purchase a four-into-one exhaust system for my '78 CB550K.  Not much choice out there???  Many people seem to have a problem with MAC.  What's the deal?  Any recommendations on an exhaust system?  Thanks!

I like my MAC. First of all it sounds good. Quiet if you want quiet but talks plenty at WOT. Like most I would rather have something else (big $ stock Honda 4/1 550F pipe) but hey, MACs OK.

Thanks bozo4onion.  Did you have to rejet or modify your carbs to run the MAC?  I'm running without the airbox and am using pods.

I had to rejet my 74 cb550.  I had pods and an open MAC.  I think I went from a 100 main to a 110.  Worked well. ;)
