Do NOT use with street bike exhausts; higher RPMs can lead to exhaust issues. HMF recommends 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. You cannot use the Torque Range Modifier with a Quiet Core at the same time, only one can occupy the exhaust space.
