Vance and Hines Upsweep 2-into-1 Full Exhaust System - Harley-Davidson Dyna
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.
Refined from decades of racing, the Vance & Hines Stainless 2-into-1 Upsweep full exhaust system for Harley-Davidson Dyna models combines stunning hand TIG-welds on lightweight 304 stainless steel with a brushed 'works' finish. It features innovative PCX™ (Power Chamber Exhaust) technology, including a chambered high-flow catalyst, to generate stronger low to mid-range torque and an unrivaled roar.

Upgrade Your Dyna's Powerband
The integration of PCX™ (Power Chamber Exhaust) technology with its chambered high-flow catalyst is key to this system's performance. It's designed to optimize exhaust gas flow, resulting in a measurable increase in low- to mid-range torque. This means more usable power where you need it most, whether you're hitting the highway or navigating city streets. The Upsweep's aggressive look and sound perfectly complement the Dyna's raw attitude. To fully capitalize on these performance gains and ensure optimal engine operation, a fuel management system and professional dyno tune are highly recommended after installation.
