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.
The Vance and Hines Upsweep Full Exhaust System brings race-proven performance to your Harley Dyna. This 2-into-1 design is hand-welded from lightweight 304 stainless steel, engineered to boost low- to mid-range torque. It's a serious upgrade for riders chasing both power and an aggressive look.
Built on decades of racing heritage, the Vance and Hines Upsweep Full Exhaust System is a testament to performance engineering for Harley Dyna models. Crafted from lightweight 304 stainless steel with precision hand TIG-welded seams, this system isn't just about shedding weight; it's about optimizing exhaust flow. The true merge collector design, combined with integrated PCX technology, enhances the all-important low- to mid-range torque, giving you more usable power where you need it most on the street or strip.
This full exhaust system is a foundational upgrade that will transform your Dyna's sound and performance. While the PCX catalyst design is emissions-compliant, a fuel adjustment or dyno tune is highly recommended to fully capitalize on the system's benefits. Tuning ensures your engine's air-fuel mixture is optimized for the increased exhaust flow, preventing lean conditions and maximizing horsepower and torque gains across the RPM range. Confirm fitment for your specific Dyna model year before ordering.

If you buy new and need to wait 1000 miles before remap. These slip ons are loud. To the point t a complete new exhaust has moved to the back burner on my upgrade wish list. Love them, highly recommend. Cannot go wrong.
Have been riding with the v&h hi outputs for over 2weeks now n they are a great upgrade from stock pipes. Nice deep sound n show quality looks. I'm taking the baffles out ASAP though I want to be loud. But it's nice to have the option.
Install took about an hour including removal of old pipes.<br />Sounds like you would expect a Harley to sound. Deep rumble and not to loud. I would recommend the purchase of a fuel pack to dial in performance.
These were fairly easy to install and made a difference in the sound. Definitely gives a Harley sound to the Ultra Glide along with a great look. Only thing that I didn't like so much was the yellowing of the tips of the pipes but im sure that will happen with just about any chrome pipes. Maybe should have gone with the black tips, but overall a very good product.
Easy to install and improves the sound! Really liking them so far!
Great looking slipon mufflers and they sound even better than they look. Very pleased with these!!
