Looks just as good as it performs! The RPM SXS Sport Muffler for the Polaris Sportsman 850 and 1000 big-bore platform is an extremely lightweight slip-on exhaust system engineered to transform the sound, throttle response, and power output of your ATV.
Featuring a specialized internally baffled, single-chamber core, this muffler eliminates severe factory backpressure to deliver a 15% increase in overall exhaust flow and a proven 2–3 horsepower bump on stock engines. Constructed from 100% TIG-welded, beautifully polished 304 stainless steel, it sheds massive dead weight—weighing in at an ultra-light 7 lbs—while easily handling mud, water crossings, and harsh trail conditions.
Best of all, this slip-on system is a direct bolt-on upgrade that requires NO ECU tuning, getting you out of the garage and back on the trail in minutes.
Directly replaces factory Polaris OEM muffler part number #1262925.
Features:
Proven Horsepower & Torque Gains: Unlocks a 2–3 HP gain and boosts exhaust gas velocity by 15% for crisper throttle response.
Deep, Aggressive Sport Tone: Single-chamber, internally baffled design gives your big-bore engine a rich, throaty sound without obnoxious drone.
Ultra-Lightweight 7 lb Design: Drastically reduces tail-end weight compared to the heavy, bulky stock muffler assembly.
100% TIG-Welded 304 Stainless Steel: Polished, premium rust-proof construction built for long-lasting durability in demanding off-road environments.
No Tuning Required: Designed to run safely and efficiently on stock factory ECU fuel maps.
100% Direct Slip-On Install: Direct OEM replacement that mounts cleanly using factory mounting locations.

Very easy to install, sounds good. Not much louder than factory, has a little grumble to it now.
Installation was very easy, specially with the use of their spring tool that I also purchased. The new muffler is smaller in size compared to the OEM muffler which will save weight. The sound is perfect as well. Would highly recommend to anyone with a Sportsman to purchase.
Was honestly skeptical considering the price. Was worried about it being cheap and flimsy but total opposite. It seems very well made and high quality. Sounds awesome but not to loud. Install was simple and it fits very well
Fantastic and easy to purchase, quick shipping to canada , easy to install, great welds and top a quality muffler. Sounds as good as it looks. They send stickers and key lanyard . Thank you .verry happy customer. Check you tube for rpm videos.
Everything fit fantastic. The only thing I would recommend is a pre-drill to use the spark arrestor. I was able to drill into it, but it wasn’t the easiest it’s made out of seriously strong metal. And just so you know your factory spark arrestor does fit.
If anything, please put a pilot hole very small, so a person can tap into it easily. That way they can use your spark screen or the factory.
2022 Polaris Sportsman XP 1000. LOVE THE SOUND AND HOW EASY IT IS TO INSTALL! I would have given a 5 star (or a 4.5 if it was possible) but as you can see in the pictures that the factory spark arrestor from Polaris (that you can remove and install in the new RPM exhaust) fits the RMP exhaust. It would have been nice if there was a note on this item or somewhere on the website that informed you of this so don't need to purchase a new one, like I did from RPM.
Havnt rode it yet but super nice muffler. Kinda wish it was lil more quieter. I wish the rpm logo was to the side and not to the bottum. Shippin was fast to canada. Easy to installl will post again after i go for a ride
Received muffler quickly and no damage. Muffler sounds great on my 2018 Polaris sportsman 1000. Tone is excellent but not to loud. Nice that I will never have to worry about packing my muffler again. Would definitely recommend this exhaust for the sportsman 850 or 1000.
Great exhaust for sportsman 850/1000! Not too loud , but a deep throaty note to it. No packing material to worry about , and no ugly rust like the factory black muffler.
Went on easy has a kick ass throaty sound, not too loud and not raspy at all, also added some power in the bottom end you won’t beat this exhaust for the price
Awesome quality fits perfectly and sounds great nice deep tone not janky like other muffler out there definitely going to buy one more for my other quad definitely worth every penny completely satisfied!!
Perfect muffler for someone that wants some more rumble but not too loud. Great quality, welds and bracket placement was perfect and the install only took 5 minutes. Highly recommend.
