- Made in the U.S.A.
- For unmodified aftermarket exhausts
- If the muffler has been modified from the original length and falls between lengths available, order the next longest cartridge available for your muffler
- When choosing a repack kit for a spark arrestor silencer, subtract 5.5" from the length of the muffler body for the actual packable length and order based on that length. Example: A FMF Turbine Core 2 with a 14" long body will have an 8.5" packable length. Order the next longest length . Use this rule for Pro Circuit also.
- Designed to pack all mufflers with core diameters between 1.75" - 2.25" and shell circumferences between 12" and 13.5"
- Measure the distance around the outside of the muffler's shell to determine its circumference
