The Little Brother to the 3" E-Valve!

Transform the quiet stock sound of your X3 SxS to the mean sound of the 3 cylinder Rotax at the push of a button! RPM SxS has incorporated a high end fully electronic exhaust valve motor into our famous Big Mouth cat delete to do just that! You now have everything the famous RPM SxS Big Mouth has WITH a electronic dump valve! RPM SxS has maintained 2.5" all the way through by utilizing a custom exhaust gasket that mates to a stock muffler! This allows you to have the most free flowing mid pipe on the market and still be able to mate it to ANY muffler that accepts the stock mid pipe! This Stainless, TIG welded  Cat Bypass frees up the absolute most HP and substantially lowers temperature radiating from the exhaust system.  Any restriction, especially the stock catalytic converter after the turbo, directly reduce horsepower.  The Big Mouth features alone will net you 6-7 wheel horsepower with the stock tune and valve closed.  All factory heat shields can be reused! OEM, or our RPM Powersports slip on muffler fits straight to this cat delete with NO modifications!

The 2.5" E-Valve give you the option to run a stock muffler, and at the flip of a switch you unleash extra horsepower, 250+ more RPM's, and a deep sporty exhaust tone! Switch it back closed and you have a quite stock sounding machine! Unlike some, our dump valve system has a smooth transition from the mid pipe to the valve allowing for the smoothest and free flowing dump valve exhaust on the market. As it passes the valve the exhaust gasses will flow out our signature & beautiful fish tail tip! If you're running a data logger or accessory that requires a second O2 bung have no worries, all RPM SxS X3 mid pipes come standard with a 2nd O2 bung at no additional cost. 

This kit comes COMPLETE all the way down to the zip ties to secure your plug and play harness! Easy to follow & full color instructions are included. Like all of our exhaust they have a Limited LIFETIME Warranty.
