The MagnaFlow Street Series cat‑back for 1999–2004 Ford Mustang 3.8L/3.9L is a direct‑fit stainless exhaust that replaces the stock system from the catalytic converter back. It uses mandrel‑bent 2.5in piping, two straight‑through mufflers and a dual split rear exit to deliver a resonant, signature MagnaFlow sound and improved flow, with CNC production for consistent fit and finish.
