My brother and I both have the RPM mufflers. At $400 they’re considerably less expensive than every other option I’ve seen out there, including the factory muffler from Polaris. They’re only slightly louder than stock but give the exhaust a deeper tone.I was going to purchase the HMF aftermarket exhaust but instead drilled out the CAT in the OEM unit. I'm so glad I did this runs so much cooler, OEM heat shield, and not one DB loader. This gives a straight through exhaust with many baffles and cost me nothing. Now I can spend the $1K on other accessories.
We had also drilled out the material in the factory muffler but didn’t like the raw exhaust sound.
