The new XDR Off-Road® Competition single exhaust system for the 2018-2023 Polaris RZR RS1, RZR XP1000 and XP4 1000 utilizes full 304S stainless steel construction, slips on the factory flanged inlet connection and is firmly held in place using the factory rubber mounts and springs. Features include a large 2.50-inch mandrel-bent inlet pipe flowing into an XDR Off-Road Competition race muffler with a 2.50-inch mandrel-bent tailpipe exiting in the stock location. The tailpipe is designed to re-use the OEM USFS qualified spark arrestor allowing you to meet stock class race rules when necessary. The cheap factory plastic heatshield is replaced with a black powder-coated steel heatshield sporting a laser-cut XDR logo that not only looks good, provides better airflow and heat dissipation but also makes the statement that you're serious about performance. As an XDR Off-Road Competition system, it will generally provide a moderate to aggressive sound level. Includes easy to follow installation instructions and all necessary hardware for a quick and simple at home installation. Note: This system does not include a catalytic converter and therefore is not emissions compliant for on-road or trail use. Competition use only.
