The Kooks 3" axle‑back exhaust with muffler is built for 2015+ Ford Mustang GT350 5.2L applications and converts Kooks X‑pipe and OEM connections to a full 3" system. It will not connect to the OEM exhaust and uses the factory quad tips. Intended to integrate with Kooks headers and X‑pipe, the axle‑back completes the Kooks system for the GT350.
