Boondocker - Polaris RZR XP Turbo / 4 XP Turbo Replacement Double-Down Muffler

The Double Down Muffler features a dual-tip, free-flowing design for ultimate performance and longevity. The lightweight stainless steel body produces a deep, pleasant tone with a clean, stylish look. Choose from multiple aluminum heat shield colors to complete your performance package.

Engineered for excellent sound quality and appearance, the Double Down Muffler for Polaris RZR uses a MagnaFlow dual-outlet core for a deep, pleasing tone. TIG-welded 2.5" outlets deliver high-flow performance built to last. The outlets accept USFS-approved spark arrestors (available separately or as an option). Dyno results show a 2–3 HP gain.

Customize your muffler with powder-coated color options for the cover and optional vanity text.
