Yoshimura RS-8 Exhaust

Chino, Calif. – July 20, 2010 – The all-new Polaris RZR 4 is the world's first four-seater sport side-by-side, and Yoshimura R&D has expanded their line of RS-8 exhausts to include this exceptional new vehicle. This new pipe will really wake-up the RZR 4's 800cc fuel-injected twin-cylinder engine, giving you more power, more torque, and better throttle response. In short, the RS-8 will transform your RZR 4 into the off-road machine it was meant to be!

The Yoshimura RS-8 is constructed from stainless steel and aluminum alloy for strength and significant weight savings, and makes great power thanks to its innovative multi-stage baffle design. That same multi-stage design also gives the RS-8 an aggressive sound without being overwhelmingly loud. The stainless steel end-cap even includes an integrated USFS-approved spark arrestor that will keep your RZR trail-friendly. The RS-8 is available as a slip-on for the 08-10 RZR, RZR S, and the 2010 RZR 4, or as a ¾ system for 08-10 RZR models.
