Description
Transform the quiet original sound of your X3 SxS into the Rotax 3 cylinder sound at the push of a button. RPM SxS has incorporated a high end fully electronic 3" exhaust valve in our famous Big Mouth cat delete and built to 3″ to do just that! Now you have everything the famous RPM SxS Big Mouth has WITH a 3" electronic cat delete valve! RPM SxS has kept 3" all the way through the electronic valve system and 2.5" in the muffler by utilizing a custom exhaust gasket that mates to a stock or aftermarket muffler! This allows you to have the most free flowing exhaust on the market and still be able to mate it to any muffler that will accept the exhaust pipe. This titanium Cat Bypass releases the most HP and substantially reduces the temperature radiating from the exhaust system. Any restriction, especially the catalytic converter after the turbo, directly reduces horsepower. The Big Mouth features alone will give you 6-7 wheel horsepower with stock trim and valve CLOSED. OEM, or our RPM Powersports slip on muffler fits directly to this cat eliminate the E-Valve system with no modifications!
The 3" TI E-Valve gives you the option to run a stock muffler, and at the flip of a switch unleash extra horsepower, 500+ RPM, and a deep sport exhaust tone! Close it back up and you've got yourself a pretty original sounding machine. Unlike some, our wastegate system has a smooth transition from the mid pipe to the valve allowing for the smoothest and most free flowing exhaust wastegate on the market. As you pass the 3" valve the exhaust gases will flow out our signature and beautiful fishtail tip! If you are running a datalogger or accessory that requires a second O2 plug don't worry, all SxS X3 RPM SxS tubes come standard with a 2 O2 plug at no additional cost.
