HMF Quite Core Insert for HMF Exhaust pipes

HMF Quiet Core Insert

 

HMF is one of the leading manufacturers in the market, making a high quality line of aftermarket exhaust systems for ATVs and Motorcycles. Almost always their exhausts are alot louder then most stock systems and so the need for a quiter exhaust with more power was needed.  HMF brought the Quiet Core Insert into the picture, which offers the power of a aftermarket exhaust, but takes away 3-6 db, making alot less old people mad. The Quiet Core is easy to install, simply remove the three screws holding the cap, insert the Quiet Core and attatch the cap once again and you are good to go.

 

Notes:

 

We recommend re-jetting the exhaust whenever a Quiet Core is installed. Failure to do so can lead to several problems and can damage the exhaust and void the warranty.

The Quiet Core will not work with the HMF Ecosystem or Quiet Race Series Exhaust because those models have mechanical cores with no room to fit the Quiet Core into the exhaust.

You cannot use the Torque Range Modifier with a Quiet Core at the same time, only one can occupy the Exhaust space
