M4 Quiet Insert - Db Reducer

Marty McMotorbikeRider - Nebraska Nice and quiet "First, I LOVE the sound of the unrestricted GP exhaust on my Honda 919. For long trips, though, it becomes quite fatiguing even with ear plugs/buds and a full faced helmet. With the insert in at highway/interstate speeds I can barely hear the exhaust over wind noise. Long rides are much more enjoyable. Don’t get me wrong I like a good sounding loud exhaust as much as the next cat, with this insert you have the best of both worlds. (I’ve had it in and out several times.) It will take you longer to walk to your tool box to find your big snap ring pliers than it will to actually install/remove the insert. On that note you do need some pretty good sized snap ring pliers."
