RPM Teryx KRX 1000 Catless Slip On Sport Muffler KRF1000
Looks just as good as it performs! The RPM SXS Sport Muffler for the Kawasaki Teryx KRX 1000 is an extremely lightweight, catless performance muffler designed to transform the sound, throttle response, and power output of your machine.
Featuring a specialized internally baffled, catless design, this muffler eliminates restrictive factory backpressure to deliver a 15% increase in overall exhaust flow and a proven 2–3 horsepower bump on stock engines. The baffled core not only produces a deep, sporty exhaust note, but also naturally functions as an integrated spark arrestor. Constructed from 100% TIG-welded, beautifully polished stainless steel, this exhaust weighs in at just 10.6 lbs—shedding a massive 14.8 lbs of dead weight off the rear end compared to the bulky 25.4 lb factory muffler while easily handling mud, water, and rugged trail abuse.
Designed as a direct 100% bolt-on replacement, it installs quickly using basic hand tools with zero modifications required!
Features:
-
Proven Horsepower & Torque Gains: Unlocks a 2–3 HP gain and boosts exhaust gas velocity by 15% for crisper throttle response.
-
Massive Weight Reduction: Weighs only 10.6 lbs—saving nearly 15 lbs over the heavy 25.4 lb stock factory muffler.
-
Catless Free-Flowing Design: Removes the restrictive stock catalytic converter to maximize flow and drastically lower radiant bed heat.
-
Deep, Aggressive Sport Tone: Internally baffled core creates a throaty exhaust note while acting as a natural spark arrestor.
-
100% TIG-Welded Stainless Steel: Polished, premium rust-proof construction built for long-lasting durability in demanding off-road conditions.

Excellent craftsmanship and quick shipping. It's a great product.
Sounds good looks good awesome product
Great product. Looks great , sounds great and fits great. Shipping was extremely fast.
Everything fit perfectly and sounds great.
It installed easy and lined up perfect and i love the sounds of the rpm muffler
This exhaust was easy to install and gave me the sound I was looking for.
Love this exhaust ! Install was unbelievably easy. Save weight as well as your right rear shock from the heat of the factory cat muffler while getting a much much better sound and looks. Not super loud, it’s just right. Welds look beautiful, much better overall appearance than factory exhaust. Could not be any happier, thanks again RPM !
Looks great, sounds amazing and was super easy to install. I would recommend this to anyone that has a krx1000. It gets rid of the 26 pound no good stock exhaust. The packaging kept it protected during shipping, and there was a koozie, stickers and a key chain. Quality product.
Fast shipping and very happy with the sound.
So many compliments on the muffler says it sound 20 x better than stock
Great sound! No popping, no custom settings needed! Just bolt it on with no finger prints! I would buy it again.
This muffler sounds and looks great. It does backfire quite a bit in low. While on high it will backfire when letting off the throttle going downhill. I don't know if this is normal. Riders behind me at night say it throws a significant blue flame. Not sure this is safe in the National Forest. I understand the disclosure of this being a "race muffler". This being the reason for a four star in lieu of five. I will state this muffler is loud, so understand that right up front.
Big improvement in the looks category over stock. Sounds great too.
It’s like a mullet not too loud in the front/idle but party in the back/when you let er rip.
Easy install sounds great!!! I like the rumble it’s not overpowering but it definitely an improvement plus it’s weighs a lot less than stock.
Looks great, sounds great, super crisp throttle response
Easy to install sounds awesome I like it also sheds about 30lbs off the stock muffler was super heavy compared to the rpm muffler
Love extra power. Sounds great

The exhaust looks great and if you really want a loud rumble you will love it. It is honestly too loud for me. I wish there was some kind of a removeable quiet core insert that you could put in it for the times you it a little quieter in the cab.

RPM SxS Teryx KRX 1000 Catless Slip On Sport Muffler KRF1000
The RPM exhaust is super light and free flowing. If you want an exhaust that screams this it!
RPM SxS Teryx KRX 1000 Catless Slip On Sport Muffler KRF1000
Excellent exhaust tone, I really like the sound. Also much lighter than stock. It is a low rumble at idle and just the tone I wanted. However It is quite a bit louder than stock while accelerating and wish the db were lower, so some might find it too loud for the trails. At the dunes it wasn’t a problem but I was definitely one of the louder machines out there, if not the loudest. Depending on where I ride I may need to put my stock pipe back on.

Sounds very good if you want loud,this is the right muffler for you sounds better than any I have heard and totally changes the machine it's odd it only adds "2-3" hp because machine feels like a totally different monster

Fast shipping Great product
Fast shipping easy installation and I was really impressed on how it was packaged it’s definitely the sound I was looking for
Installation was a breeze. It went on faster than it took to remove the old one.
Sounds great looks great
Worked great. Easy installation.
Put on one of my shop builds and it fits great.
Fast shipping looks and sounds good
my engine runs a little cooler. There may be a small increase in power but if there is, it is very slight. The exhaust tone is more pleasing to listen to. The replacement job was very doable, even for a 78 year old man. Thank you for your dedication to excellence.
Was easy to install and love the look and sound would buy again
Muffler was great fit perfect took about an hour to install. It sounds good would recommend it.
