How do we make the industry’s best-selling X3 Muffler better you ask? We incorporate RPM SxS’s trademark E-Valve system into it! Our E-Valve allows us to bypass the muffler and send exhaust notes STRAIGHT out the back creating an insanely awesome sound X3! Flip the switch back to closed and you’re back to the RPM SxS X3 Sport Muffler! When closed this is not an obnoxious straight-through system that provides no back pressure and sounds horrible, this system utilizes a high flow muffler following the stock exhaust bends and utilizes the stock muffler tip, and exits the stock location. A stock spark arrestor can still be used! Built to utilize the OEM rear fascia.
