RZR Turbo R and PRO E-Valve Muffler
Take full command of your Polaris RZR's exhaust note and horsepower at the flip of a dash-mounted switch! Featuring RPM SXS's trademarked E-Valve system, this slip-on muffler combines the refined performance of our high-flow catless Sport Muffler with an unrestricted, valve-actuated bypass tip.
When closed, exhaust gases route through our 304 stainless steel sport muffler core to deliver a clean, deep rumble with a 3+ HP gain on stock tunes. Flip the backlit switch to open the integrated 2.5" bypass tip—located directly at the end of the mid-pipe—and you instantly unleash a straight-through exhaust path for maximum turbo spool whistle, an aggressive tone, and up to 7+ HP and 500+ additional RPMs under load!
By completely eliminating the restrictive factory catalytic converter, this system drastically lowers Exhaust Gas Temperatures (EGTs) and under-hood heat soak. It is built from mirror-polished 304 stainless steel with show-quality TIG welds, mates directly to stock or RPM mid-pipes, and includes a full plug-and-play wiring harness. Designed for ultimate versatility, it can be run behind your factory rear plastics or paired with the RPM Rear Fascia Delete for a full-open chassis look!

-
Trademarked E-Valve Dual Sound System: Run in stealth closed mode for a deep sport tone, or flip the switch to open the 2.5" bypass tip for wide-open turbo roar and maximum power.

Little louder than stock but not by much with the dump closed. Ordered the quite baffle with it just in case and more than likely won't use it. With the dump open it sounds awesome.
Very nice products. Sounds great very quiet probably equivalent to factory exhaust through the muffler maybe a little bit deeper sound. Definitely pretty rowdy with the open exhaust.
Very easy install and sounds great open or closed.
Fast delivery, easy to install, sounds great !
I love it nice sounds to he only ting is they don’t send stickers anymore
Super load and good tone. Makes all my friends jealous.. Highly recommended
Extremely pleased with the new exhaust. Louder than I expected but actually really like the way it sounds
Absolutely love this exhaust. It brings the Turbo R to life and makes it sound like a beast. I can't recommend this enough
Sounds great, was easy to install.
Great exhaust if you like the cut out option. Fit perfectly no problems from what i see. Sounds pretty good open and closed. Closed it’s basically a good sounding stock muffler. Open its LOUD!
It’s like a glove love the look of it too sounds amazing thank you
Fits like it’s supposed to sounds amazing
Easy install hood fitment
This thing looks cool and sounds even better. Fits like a glove.
Great sounding muffler. Slightly louder than stock, with a deeper tone. Seems a little louder than the RPM sport muffler on our other Pro, but not by much. The e-valve works great and really makes it bark when ran in the open position. Installation was a breeze, also. Exhaust cover fits perfectly and really looks great as well.
Very easy to install by your self,sounds amazing, definitely worth the money!!
Sounds amazing to much bumble wrap
I love the looks of it and the sound is amazing.
The exhaust sounds amazing and was easy to install the only issue I had is where the harness plugs into the exhaust I had to cut the factory plastic in order to plug it in but I don’t know if that’s an issue with the exhaust or the Polaris plastic but it was worth the money
Love it
Easy install and sounds great:)
