Yoshimura POLARIS RZR XP900 Signature RS-4 FS SS-SS-CF

Stainless Steel Header / Stainless Steel Muffler / Carbon Fiber End-Cap

The RS-4 Full System is impressive. It’s CNC mandrel bent using polished 18-gauge 304 Stainless Steel tubing for a long lasting, durable and rust-resistant life. Headers feature an over-sized step tube design for maximum power throughout the entire RPM range. Argon purged MIG welding ensures absolute top-quality fit and finish. Put it all together and you have a full system that is over three pounds lighter than the stock unit and increases overall power from idle to redline. In addition, the RS-4’s premium muffler packing helps meet the USFS noise specifications. The RS-4 comes with USFS approved spark arrester installed.
