Exhaust - Core (15" EVO/ECO Muffler)

Big Gun’s 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

Notes:
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 us for assistance.
