Polaris XPEDITION XP & ADV Sport Muffler
Unleash hidden horsepower and give your Polaris Xpedition an aggressive, deep exhaust note with the RPM SXS Slip-On Sport Muffler! Engineered specifically for the Xpedition platform, this 304 stainless steel, TIG-welded muffler replaces the restrictive factory unit using all OEM mounting hardware—and is built with a low-profile design that does not interfere with bed dumping or utility use.
Featuring a proprietary interior chambered baffle with a free-flowing pass-through design, this muffler delivers a proven minimum 5 HP gain on a stock machine, with substantially higher gains unlocked on Stage 1+ tuned setups. By significantly lowering exhaust gas temperatures (EGTs) and eliminating backpressure, it provides the airflow needed for maximum performance. Best of all, it installs in just 10 minutes and delivers a rich, satisfying sport rumble that sounds incredible without causing annoying cab drone or leaving your ears ringing after a full day in the backcountry.

Customer Reviews
Overall rating: 4.9 / 5 from 42 reviews.
Super easy install. Great finish and fits just as good as OEM...As far as sound goes, the numbing drone sound in the cab noise from the stock muffler is gone. The exhaust truly does now sound like it is outside of the machine...This product is far better then stock.
Wow! I was a little skeptical about the reviews on reducing the noise level inside the cab like they advertised. Wow! Big, big difference. Highly recommend the RPM slip-on muffler . I've made several upgrades this should have been the first upgrade! Thanks RPM for the great products!
Love the RPM exhaust, sound, look, and most of all price! RPM product management if you guys read this look into offering an exhaust with a 4in tip like I added. I’m sure people will buy this option too! Thanks RPM for an affordable option!
Fit really well, Cost me over 600.00 CDN by the time I got it, was expecting better finish quality, You can see grind marks and pretty poor looking welds compared to other mufflers. Quieter than stock at idle and low rpm and doesn’t resonate in the cab as much as the stock one. You have to drill your own hole for the stock spark arrestor.
It looks way better than the OE muffler but way louder.
It is not much louder inside the cabin but it got rid of the DRONE that i hated so much.
Over all I'm happy with this muffler.
Works better than expected. Not sure if its quieter or not, about the same.
But reduced back pressure allows clutch (EBS) to grab easier and actually hold on decents.
I wanted to get rid of the catalytic converter to cut down on the heat back there. And I wanted to keep my factory muffler intact for any warranty repairs.
It works great and the sound inside the cab is more pleasant.
I didn’t notice a lot of difference on the bottom end, but I saw a huge difference on the top end. I was able to go from 40 to 60 muck quicker. It seems to let the engine breathe a lot better. I just added the Gilomen clutch and ECU tune and it is amazing. I have whole new machine.
