Vance and Hines Twin Slash Slip-On Mufflers - Harley Softail Fatboy
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.

These slip-ons bolt directly onto your stock headers, delivering a custom dual slash-cut appearance and an aggressive exhaust tone.
