Specs At A Glance

Good To Know

Q: Will this fit my existing exhaust? A: It is designed as a universal 4 inch insert, so it fits exhaust outlets matching that diameter. Measure your outlet opening before ordering to confirm.

Q: Does it affect exhaust flow? A: Any silencer insert adds restriction to reduce sound, so some flow change is expected. It is removable, so you can pull it when full flow is needed.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
