The FMF PowerCore 4 Slip-On Muffler is a four-stroke exhaust upgrade built for riders who want more flow and better sound than stock, making it the direct answer for the FMF PowerCore 4 slip-on muffler exhaust search. FMF builds the PowerCore 4 around an extruded aluminum canister and a MIG/TIG welded stainless steel mid-pipe that's lighter and stronger than the exhaust that came on your bike. Throttle response feels crisp when you're rolling on out of corners because the hi-flow core pushes exhaust gases out faster than a stock unit. FMF has been doing this long enough that the PowerCore 4 design isn't a guess.
- Delivers more exhaust flow by using a hi-flow core with increased surface area.
- Built from an extruded aluminum canister so it's lighter than stock without sacrificing strength.
- Channels exhaust gases through a MIG/TIG welded stainless steel mid-pipe for long-term reliability.
- Keeps the packing working longer with space-age internal materials that absorb more sound.
- Fits trail riding requirements with a U.S. Forestry approved maintenance-free spark arrestor exhaust muffler screen.
