Anybody try it? Too noisy?
IIRC, that was in an article about hotting up airheads printed in the early '80s, along with a bunch of other performance tips. I'd been reminded of that tip when I was looking at the pics of the disected muffler earlier too.

I'm quite reluctant to try that on my S/S Keihans, but am interested in feedback from anyone who has . . .
