A little history, I has a 2016 Polaris XP 1000 and we used to wear earplugs while riding the trails as it would get annoying after a while in stock form. I switched to a Cam-Am X3 and it was super quiet and loved it. We bought a family machine in 2019, the Polaris Turbo S 4 and it is pretty quiet from the little we have drove it, but the heat soak we see in the 20 miles we have on it concerned us. So we went on the hunt for quiet mufflers that removed the cat.Utah RZR Rentals
We found it with the HMF Titan QS. It is a dual exhaust and works! I have sound clips and the install here if interested.
