Description
The Big Mouth features alone will net you 6-7 wheel horsepower with stock trim and closed valve. OEM, or our RPM Powersports slip on muffler fits directly to this jack eliminating the E-valve system without modifications!
The 3" E-Valve gives you the option to run a stock muffler, and at the flip of a switch you unleash extra horsepower, 500+ RPM, and a deep sport exhaust tone! Close it back up and you have a pretty original sounding machine. Unlike some, our wastegate system has a smooth transition from the mid pipe to the valve that allows 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.
This kit comes COMPLETE all the way down to the zipper ties to secure your plug and play harness! A replacement exhaust bracket is included to incorporate the 3" exhaust! Easy to follow and full color instructions are included. like all of our exhausts they come with a LIFETIME, NO questions asked warranty!
