This bolt-on XDR Competition exhaust system is designed specifically for the 2015-2020 Polaris RZR 900 2 and 4 door models with the naturally aspirated engine, including 900S models. Features include 409S stainless steel construction, a 2.25-inch mandrel-bent inlet tube flowing into the "straight-through" cross-flow XDR Competition muffler that provides a deep moderate to aggressive sound level.

The system also comes with a laser-cut heat shield to protect the factory plastic rear valance. Includes all necessary hardware and detailed instructions for a simple at home installation.
