HMF Performance / Titan / Swamp Series Quiet Core Insert

The HMF Quiet Core is an insert that installs on most HMF exhausts in just seconds. It is designed for sound sensitive riding areas and decreases the sound level approximately 3-6 dB.

• Fits HMF Performance, Titan, and Swamp series
• Does not fit HMF Competition Series, Performance Big Core systems, or Titan SS Big Core systems
• DO NOT use with street bike exhausts as higher RPMs can lead to exhaust issues
• It is highly recommended to pair with HMF Spark Arrestor Insert as this will reduce or eliminate any unwanted vibration of the Quiet Core
• Retuning may be necessary when a Quiet Core is installed; failure to do so can lead to several problems and can damage the exhaust and void the warranty
