The world of side by side and UTV performance is expanding at a rate faster than the galaxy is. These things have become a hot rodder’s dream with stout engines from the factory that can be hot rodded with the same types of stuff that you do to cars or trucks on the street. Flowmaster is leading the charge with their XDR exhaust systems and if you have a 2015-2018 Polaris RSR 900 or 900S you can take advantage of the XDR gains with this new bolt on system.

This new bolt-on XDR performance exhaust system is designed specifically for the 2015-2018 Polaris RZR 900 2 and 4-seat versions with naturally aspirated engine, including 900S models. Features full 409 stainless steel construction with a 2.25-inch mandrel bent inlet tube flowing into the XDR performance cross-flow muffler and includes a bolt-on stainless steel heat shield. The dual 2.25-inch mandrel bent tailpipes are tucked up high within the rear fenders providing a moderate to aggressive deep sound level and contain USFS qualified spark arrestors allowing you to meet stock class race rules when necessary. The system is finished off with a pair of 3.50-inch brushed 304 stainless steel tips with black anodized CNC-machined aluminum end caps exiting above the factory rear valance. Includes all necessary hardware and installation instructions for a simple at home installation.
