This new XDR Competition single exhaust system for 2016-2020 Polaris RZR XP turbo and XP4 turbo is constructed from 304S stainless steel for good looks, while the internals of the competition muffler is fabricated with 409S stainless steel for durability and longevity. The system slips on at the factory flanged connection and is firmly held in place using the factory rubber mounts and springs. Features include large 2.50-inch mandrel-bent tubing flowing into an XDR competition race muffler with the mandrel-bent tailpipe exiting in the stock location. The tailpipe is designed to re-use the OEM spark arrestor allowing you to meet stock class race rules when necessary. The cheap factory plastic heatshield is replaced with a custom black powder-coated 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. The XDR system provides a deep 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. For Competition use only.
