Polaris RZR E-Valve Pro R Chambered 3" Performance Exhaust ~ Electric Valve Muffler

Polaris RZR Pro R Chambered 3" Muffler   How do we spice up our famous Chambered Pro R Muffler? Add a Electric valve of course!  With Our Pro R Chambered muffler being the most in demand muffler to hit the Pro R market we knew it was time to add an electronic valve to it for the guys who want quiet AND wan to let it sing when its time! We modified and mechanically baffled the crossover chamberers to our standard Chambered Muffler and add a E-Valve directly in the first chamber that allows exhaust to bypass the chambers and directly enter the exit chamber of the muffler.  Technically this muffler with the valve closed is quieter than the standard Chambered Muffler AND has the ability to out perform it with the valve opened.
