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.

Common questions
Will these slip-ons fit my 2010 or newer Dyna?
No, these Vance & Hines Twin Slash slip-ons are specifically designed for 1991-2009 Harley-Davidson Dyna models. Newer Dynas typically require a different slip-on kit due to changes in exhaust design.
Do I need a fuel tuner after installing just these slip-ons?
While not always strictly required for basic operation with slip-ons alone, adding a fuel or air recalibration device can help optimize your engine's performance, especially if you plan on further modifications down the line.
Are the heat shields included with these slip-ons?
Yes, these slip-on mufflers come with full coverage heat shields to ensure a clean, finished appearance and to protect against heat discoloration.
