Our replacement Race Core is compatible with current-style EVO or ECO Series mufflers. The Race Core is offered in either 13 ¼” or 15 ¼” length depending on the length of your muffler.
- Compatible with various current-style EVO and ECO Series mufflers that have a 15″ overall muffler body length (not including the end tip)
- 13 ¼” (inch) total length
- 1 ⅞” straight-through diameter
- 304 stainless steel perforated core
- Check the length of your muffler body to determine the correct size needed.
- Some older model mufflers had different core diameters and both ends need to be measured to ensure you need 1 ⅞” diameters on both the inlet and end tip side.
- If you need a core with a different diameter than what is offered here, contact a Big Gun sales rep for assistance.
