Is your WerkesUSA exhaust a little too loud? Bolt this in to reduce the db's by about 8-10%

The Large Exhaust insert fits WerkesUSA slip-ons with 2.00" (50mm) diameter exit.

Dual exhausts require two inserts

For exhaust with 1.625" (41mm) exits please see our Small Insert

**Note: ONLY compatible with WerkesUSA exhaust with 3 mounting bolts in the exit of the muffler.**
