Have you lost your stock heat shield, or need one on an aftermarket head pipe? FMF makes this nice unit that includes clamps, heat shield with the FMF logo and button head screws to hold it on. We recommend Anti-Seize on all exhaust fasteners.
This Quiet Insert comes stock in all new FMF Q4 mufflers. If you lost yours, this is the replacement you need.
It will fit Q4, Q4 Hex, Powercore and Powercore Hex mufflers.
It will reduce the sound rating of the Power Core models, from about 99db down to about 96db.
Please choose the correct Insert for your muffler. If you are unsure of the year that your muffler was manufactured you can easily identify visually which insert you will need.
