Description
Overview
The XDR Competition Polaris Exhaust System Kit is a bolt-on performance exhaust system engineered specifically for 2015-2021 Polaris RZR 900 2 and 4 door models with the naturally aspirated engine, including 900S models and RZR Trail 900 models. Built from durable 409S stainless steel, this complete exhaust system replaces the restrictive factory setup with a free-flowing design that transforms both sound and presence. If you’ve been searching for the right performance exhaust to shop for exhaust upgrades on your RZR, this XDR kit delivers a purpose-built, competition-ready solution.
At the heart of the system is a “straight-through” cross-flow XDR Competition muffler fed by a 2.25-inch mandrel-bent inlet tube. That mandrel-bent exhaust pipe design maintains consistent diameter through every bend, promoting smooth flow while producing a deep, moderate-to-aggressive sound level. Dual 2.25-inch mandrel-bent tailpipes are tucked up high within the rear fenders and finished with a pair of 3.50-inch brushed 304 stainless steel tips featuring double-wall construction and black anodized aluminum end caps for a bold, aggressive look.
Key Benefits
This catback-style exhaust system is designed for a straightforward, at-home installation. It ships with all necessary mounting hardware and detailed instructions, along with a laser-cut heat shield that protects the factory plastic rear valance from tailpipe heat. Whether you’re comparing it against other performance exhaust options like Borla exhaust, Corsa exhaust, MagnaFlow exhaust, or Walker exhaust builds, the XDR Competition system stands out as an application-specific car exhaust designed to fit and perform on the RZR 900 platform.
