About Vance and Hines

Vance & Hines has been building motorcycle exhaust since 1979 and has run factory-backed drag and King of the Baggers programs that feed straight back into its street products. Systems like the Torquer and the 2-into-1 designs are engineered around real dyno work, not just sound — which is why they show up on so many tuned Milwaukee-Eight and Twin Cam builds.

Great Slip-Ons!!

They are awesome! A deep throaty sound but not obnoxiously loud. And they look great.
