Roush Black Tip Axle-Back Exhaust Kit Mustang V6/ EcoBoost W/O Active 25-26

When your 2015-2026 Mustang needs a sound upgrade, this exhaust kit (421837-BLK) delivers. It provides your V6 or EcoBoost model with an exhilarating auditory impact.

The innovative open-chamber design negates the use of traditional fiberglass packing materials. Installation is straightforward and uses factory hanger locations.
