Vance and Hines Twin Slash 3" Slip-On Mufflers - Harley Softail
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.
Transform the sound and performance of your 1991-2009 Harley-Davidson Softail with Vance and Hines Twin Slash 3" Slip-On Mufflers. These slip-ons are a direct bolt-on replacement for your factory mufflers, delivering Vance and Hines' signature throaty exhaust note. Experience an immediate upgrade in both acoustics and usable torque.

- Direct bolt-on replacement for stock mufflers
The Vance and Hines Twin Slash 3" Slip-On Mufflers for Softail models feature advanced PCX™ (Power Chamber Exhaust) technology, incorporating a chambered high-flow catalyst cartridge. This innovative design not only enhances the exhaust note to a rich, aggressive tone but also actively works to increase torque output, giving you more grunt where you need it. The distinctive twin slash 3" cut tips provide a classic, custom look that complements the lines of your Softail, while full-coverage heat shields ensure a clean, integrated appearance and rider comfort.
Performance and Sound Unleashed
- PCX™ chambered high-flow catalyst cartridge increases torque
- Signature throaty exhaust tone
- Twin Slash 3" cut tips for a distinctive look
- Full coverage heat shields for a clean aesthetic

Easy Upgrade for Your Softail
Designed for straightforward installation, these Twin Slash slip-ons mount directly onto your existing stock head pipes, making it an accessible upgrade for any Softail owner. While slip-ons alone typically do not necessitate an ECM tune, pairing them with a high-flow air intake and a fuel management system can further optimize your bike's performance. Confirm fitment for your specific 1991-2009 Softail model to ensure a perfect match.
