SILBER TURBOS BRP CAN AM X3 SHOCKER DOWNPIPE (ELECTRONICALLY ADJUSTABLE EXHAUST!)This is one of the coolest products we've ever built. With the push of a button, you can open a dump valve on the downpipe. This does two things, first it makes the 3 cylinder Rotax absolutely sing. Second horsepower, with most customers seeing a jump of 200 300 RPM when the valve is opened. Want to keep things quieter and more stock like? No problem, just press the button and the valve will shut, with your exhaust retaining a softer more gentle note
