The MagnaFlow Street Series Cat-Back Performance Exhaust System 15671 is engineered to provide a resonant, powerful engine tone and dyno-proven performance for the 4.6L SN95 Mustang. This system features a direct-fit design, utilizing extensive 3D scanning to ensure it bolts directly to factory mounting points from the catalytic converter back.

Constructed from durable, corrosion-resistant stainless steel, this kit uses CNC precision robotic manufacturing for consistent fitment and longevity. The fast-flowing 2.5-inch mandrel-bent main piping reduces restriction compared to the OE setup, while two straight-through mufflers maintain high-flow velocity. The system exits in a dual split rear configuration finished with 3.5-inch polished clamp-on single-wall angle-cut tips.
