HMF Quiet Core – 6946006

Features:

• 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
