Delivering a proven3 horsepower gainwhile removing approximately6 poundsfrom the sled, the Vari-Sound Muffler improves both performance and riding enjoyment. Riders can instantly switch between a quiet trail-friendly exhaust tone and an aggressive free-flowing performance exhaust using the included wireless remote control.
With the valve in the closed position, exhaust is routed through the Straightline Performance muffler, producing a deep, refined sound that remains comfortable for long trail rides and noise-sensitive riding areas. When the valve is opened using the remote control, exhaust is redirected through a dedicated side outlet, creating a more aggressive performance tone and allowing exhaust gases to exit through a less restrictive path.
Constructed entirely from premium polished stainless steel, the Vari-Sound Muffler is built for durability, corrosion resistance, and long-term reliability. The system also incorporates an aluminum outer heat shield housing that helps manage heat while providing a clean, factory-quality appearance.
Each kit includes a precision-engineered aluminum side-panel outlet trim ring designed to provide a professional finished appearance when installing the outlet through the side panel. The trim ring ensures a clean fit and finish while protecting the panel opening.
All electronics are plug-and-play and connect directly to the vehicle’s accessory power system. The complete wiring harness, electronic valve assembly, wireless remote, mounting hardware, and trim components are included for a straightforward installation.
