Just found this Forum and decided it would be nice to bounce questions about my trike off someone else who might know more than all my older, 2 wheel riders like myself. I bought my 1999 Harley Davidson Ultra-Classic/Lehman trike in 2015, and haven't had much time to do anything to it, other than ride it on occasion. I retired 2016 and downsized from a 7 room house with a 3 car garage, to a mobile that needed upgrades, and a shed that needed to be totally rebuilt, which I finished just before this winter set in. Anyway, now that I have a place to work on my trike, I'll start working on it. My first question is, does the Lehman trike conversion use regular touring exhaust systems? Anyone know??? Thanks!
