The MagnaFlow Street Series Axle‑Back for 2005–2009 Ford Mustang (4.6L/5.4L) adds a deep, resonant signature tone and dyno‑proven flow gains using mandrel‑bent 2.5in piping and two straight‑through mufflers. Dual split rear exit with 4in polished double‑wall tips gives a finished look while producing moderate exterior and mild interior sound. The axle‑back design replaces rear components for an easy, direct‑fit install.
