$389.95 USD
Polaris RZR XP1000 & RS1 Sport Muffler, Slip-On Sport Muffler
Uncork restricted horsepower, slash engine bay temperatures, and upgrade your exhaust note with RPM’s Stainless Steel Slip-On Sport Muffler! Engineered specifically for the naturally aspirated Polaris RZR XP 1000 and RS1 platforms, this high-flow slip-on replaces the restrictive, heat-soaking factory catalytic converter to deliver a guaranteed +3 horsepower increase on a bone-stock machine while drastically lowering exhaust gas temperatures (EGTs). If you are running an aftermarket ECU flash, this free-flowing design is an absolute requirement to unlock the full potential of any Stage 1 or higher tune.
Say goodbye to obnoxious, raspy trail drone. The RPM Sport Muffler is acoustically tuned to produce a rich, deep, and sporty exhaust tone that wakes up the ProStar engine without leaving your ears ringing after a full day of riding. It maintains a clean, factory-stealth appearance by seamlessly reusing your original rear fascia, heat shields, mounting hardware, and OEM USFS-approved spark arrestor.
Installation takes just 10 minutes using basic hand tools. The muffler slips directly onto your stock factory mid-pipe or pairs seamlessly with the high-performance RPM SXS E-Valve Mid-Pipe using original chassis hanger locations—no cutting, welding, or tuning required.

Love the sound and the look of it .It was a much needed addition to the vehicle.
3 to get delivery easy to install 10 minutes you pulled to Springs face plates two bolts for exhaust comes off sounds pretty nice I will say it's two notches higher than stock you can definitely still hear the music over the music gives it stock sound at lower rmp loud sound a high rpm definitely good sound
This is a great muffler. It’s got a nice low throaty tone at an idle, but it barks pretty good when I’ve got my foot in it. It doesn’t look far from stock, so the cops don’t even question it. My machine is much more fun to drive now. I definitely recommend it.
Bought this for my buddies 1000 Polaris xp and definitely sounds way better then the stock Polaris muffler he just loves it. Another thing was the shipping was super fast arrived in 3 days and the price was half of what other mufflers cost would definitely buy from this company again thanks for the great service and awesome muffler.
Shipping was great product was excellent has an amazing sound. Would definitely recommend to anyone looking for aftermarket muffler that is not looking for strictly race sound
