the latest twin cams have a computer controlled butterfly in the exhaust to sneak them thru the noise checks
rebuilding my shovel with a 2 into 1 header pipe and straight thru fish tail
previously this system worked well but was tad noisey
using the butterfly valve out of a twin cam manually operated via a cable and advance retard lever I should get the best of both worlds - efficient exhaust system and noise control when it's needed
