Harley Baffles & Baffle Repack Kits

Though Harley baffles are often removed to make louder exhausts, more care should be taken because of the important role that they play. Baffles create backpressure, which is necessary for the engine to run at its peak and to have the best fuel mileage. A baffle is simply a metal tube with holes that is installed into the end of the muffler. The holes are what creates the backpressure by diverting the air instead of shooting straight out the tail pipe.

In addition to creating backpressure, Harley exhaust baffles also influence the sound and decibel level of your exhaust. The holes in the baffle help to muffle the sound and lower the decibel rating. Choose quiet baffles if you want to make your bike quieter, which is a great idea for commuters and residential riders. Some baffles are wrapped with fiberglass to further muffle the sound. This fiberglass packing deteriorates over time and needs to be repacked. That job is simple with a muffler repack kit. Less restricted baffles will produce more rap and a louder note.
