1977 cb550 straight 4 into 2 exhaust. (Baffles removed.)

1977 honda, cb550, exhaust, straight pipes
Baffles rattling? Rip em out! My left baffle was rattling very badly. There was no way to get to it because of the turn out on the end of the pipe. This caused me to cut the ends off with a pipe cutter and while I was in there, rip out the baffles. Then I welded the ends back on but turned down a bit more. I like the way it sounds. It is loud, but I ride with a bunch of Harley’s with straight pipes. It feels more powerful this way as well even without a rejet, although it was already jetted for a fuller flowing exhaust.
