Easy install, still sounds good. Just alittle less noise. You can also use the stock spark arrestor behind the baffle. It least on a Can Am x3 turbo maverick R......
RPM Muffler Baffle / Quiet Core
If you are looking to tone down exhaust volume and drop decibel levels without sacrificing high-flow engine performance, the RPM SXS High-Flow Quiet Core Insert is exactly what you need! Engineery-built specifically for RPM SXS performance mufflers and exhaust systems across Can-Am and Polaris platforms, these high-flow perforated inserts tame harsh exhaust bark and drone for noise-sensitive trails, forest areas, or neighborhood riding.
Constructed from heavy-duty stainless steel, the perforated baffle design allows exhaust gases to pass through efficiently—maintaining smooth airflow velocity and performance while taming overall decibel output. Installation is straightforward and requires drilling a single small hole in the exhaust tip to secure the core solidly in place using the supplied hardware.
Features:
-
Decibel Reduction: Lowers sound output and tames harsh exhaust bark for a quieter, drone-free ride on noise-restricted trails and long rides.
-
High-Flow Perforated Design: Engineered to reduce exhaust noise while maintaining smooth exhaust gas flow and turbo/NA performance.
-
Heavy-Duty Construction: Built from thick-gauge stainless steel to handle extreme exhaust heat, backpressure, and severe off-road vibration.
-
Integrated Spark Arrestor Option: Pro R variation includes an integrated spark arrestor for total forestry compliance and safety.
-
Secure Bolt-In Fitment: Includes all required mounting hardware to lock the quiet core firmly inside the muffler outlet.
-
RPM SXS Specific: Precision-sized exclusively to fit RPM SXS performance exhaust lineups.
What's Included in the Kit:
-
(1) RPM SXS High-Flow Perforated Quiet Core Insert (In Selected Size/Model)

Product as described
Not sure. More than likely won't use it. Muffler isn't bad without it. Slightly louder than stock.
Definitely works. At 35mph the cab noise was about 96DB in the drivers seat, now with the core it’s hovering around 91 DB. Good addition if your trying to have a conversation while riding
Its just what it says fits great
I used for a different application, but it did quiet down the exhaust on my Jeep.
I had to trim the inner pipe on the outlet for the baffle to go in flush. Marked and drilled hole in outlet for baffle hold-down screw. Little work trimming and drilling s.s. 👍👍
Love the look and sound easy to install just installed RPM BOV can’t wait to hear it this weekend
RPM Motorsports, I wanted to take a minute to provide a review of your products. This has been a while in the making as my 2022 Can-Am X3 Turbo RR was delayed for several months. While waiting, I patiently accumulated my build parts and RPM Powersports was chosen for some of the most important pieces. I'm running the RPM Big Mouth 2.5" mid-pipe, Sport Exhaust, blow-off valve, and catch can along with the most recent addition of the quiet core insert. I was impressed with the fitment, finish, and quality of your products. Now after finally getting some seat time and a few hundred miles on the car at the dunes, trails, and everywhere in between all I can say is WOW! The exhaust system by far is a crowd pleaser and the tone is amazing. The song it produces when accelerating and my personal favorite is the burble when lifting off the gas. It just sounds so good! If I had one regret it would be that I didn't get the Ti captain's choice mid-pipe right off the bat. I've been super happy, to say the least, and today got to experience your exemplary customer service. The catch can was the last part to be installed and at some point in the build, I lost the cap to cover the stock intake port. I called RPM customer service, got to speak to a real person, and after admitting my mistake, you still refused to take my money and are sending me a replacement part free of charge. The customer experience is almost a lost art these days and you guys definitely haven't forgotten that crucial part of the business. Great products with great service to back them up. You have earned my business and I definitely will come to RPM first for future Powersports needs. Thanks again, Darrin Puljan Bonney Lake WA
don't fit the exhaust poor looking welds waist of money!
Worked great was able to hear my passenger
The baffle fit perfect. And I was able to still use the factory spark arrestor after the baffle !
It fits perfectly actually went in different manufacturers exhaust with same diameter pipe but works great
Took some of the high-pitched sharpness out of the tone and created some back pressure. Fit right in the exhaust pipe. Easy install
Fit perfectly and very well built
The race sxs Exaust made it hard to hear coms/radio traffic, with the muffler insert it’s incredibly quieter and were able to hear a lot better.
It did exactly what I wanted to do
It did reduce the noise some. It was worth it. Thanks
It was a perfect fit makes the exhaust sound even better great product
Easy to put on
Grteat
made a huge difference for my poor kids in the back seat, still has an amazing tone (RPM sport muffler)
Fit good. Sounds good.
Great
Fits and works great
Product is exactly as described, and I always love RPM products! They are great quality, and you get what you order. I haven’t installed it yet to give feedback on noise difference, but plan on doing so soon. Thanks again!!
works well
Works like a charm, the tone got deeper. Great product
Made my RPM Sport muffler actually bearable. Huge difference in sound!
Nice fit, good quality and perfect sound
Much quieter perfect fit p
Fit perfectly in my 3 1/2” stainless tailpipe, mellowed exhaust and reduced drone. Just what I wanted.
Quality products
It fits but it is not snug enough. Doesn’t change sound much
Had to ship back waiting on a refund I was trying to get one for the 3” pipe I bought off you guys but someone I talked too said you didn’t make one for it I think this one was for a stock xp1000 exhaust
works good still sounds great.
Yo instale un mofle magnaflow en un rzr polariz 1000, el sonido me gusto pero ,creo que muy fuerte aparte tengo como un back fire o un tronido,despues de instalar el buffle quien core,el tronido desaparesio y se escucha muy bien mas sport estoy contento.lo recomiendo
Actually lowered the noise on my stock exhaust. So that I can drive it through the neighborhood and listen to my music without the loud noise of my exhaust.
Oh it’s dope and it’s actually dampen the sound.
I don't like it at all
