Polaris RZR Pro R 3" Sport Muffler Exhaust
Give your RZR Pro R the sound and performance it should’ve had from the factory with the RPM 3" Sport Muffler Exhaust. This system is designed for riders who want a deeper, stronger exhaust note without going full “race pipe loud.” The high-flow 3-inch design frees up exhaust movement, drops backpressure, and wakes up throttle response—while keeping volume trail-friendly and clean.
Built from TIG-welded 304 stainless steel, the Sport Muffler is extremely durable and ready for heat, abuse, and big-horsepower riding. The internal sport-tuned core delivers a rich, aggressive rumble under throttle but stays smooth and controlled at cruising speeds. It bolts directly to factory mounts and works great on both stock and tuned Pro R machines.
This is a 304 stainless FULL 3" catless sport muffler that utilizes a internally baffled perforated core. By utilizing not just a straight through muffler we were able to achieve a beautifully sounding exhaust tone while staying extremely light weight and retaining the use of the factory rear fascia. This is a full 3" out the tip design achieved by using the supplied, RPM designed, OEM appearing stainless 3" tip. Mounting is done by utilizing the factory hangers & brackets. The Sport Muffler lands in the middle of the "loudness chart" for our Pro R line up. Loudest being the Race Muffler, and nearest to stock sound would be the Chambered Muffler. If you're liking this muffler and want something a touch quieter we do offer this same set up in a DUAL Sport Muffler! The video at the bottom of this page compares all 3 to make your choice easy!
The factory rear fascia the exhaust exits from was designed around the exhaust tip, this design is called a "Isosceles Trapezoid". The absolute biggest downfall of the factory exhaust is this....The inlet of the factory muffler is 3", with the restriction of the factory catalytic converter it is bottlenecked at the exit & tip which are reduced to 2.5". This was the bottleneck of the exhaust system that needed addressed. While others struggled to "design" a exhaust tip that fit the factory rear fascia, we got to it and knew what needed to be done. Rather than use a typical "car" style exhaust tip we knew we must retain the factory shape. We painstakingly re-designed the factory tip using 3D scans and models. After building our press molds, testing, re-building, and test fitting, we finally achieved a finished product. A factory like 3" tip that appears OEM and perfectly fits the OEM rear fascia. Our tip can be easily modified to be countersunk in the rear fascia providing a more sleeker look.
We have for years manufactured our own replacement OEM style gaskets, with this knowledge & experience we knew that we needed to replicate the OEM flange for best performance. While some attempt to use cone style sealing flanges, we replicated the OEM flange in order to preserve gasket life. No pressure points, only evenly distributed gasket pressure for maximized sealing.
