Product Description

The MagnaFlow 24151 is an HM Grade direct-fit catted H-pipe engineered specifically for the 2005-2010 Ford Mustang GT with the 4.6L V8, in both Coupe and Convertible configurations. Its H-pipe crossover design equalizes exhaust pressure across both cylinder banks, reducing back-pressure for improved high-RPM power while maintaining emissions compliance. Developed with advanced 3D scanning technology for factory-accurate fitment, this mid-pipe bolts directly onto stock manifolds or shorty headers without cutting or welding.

Built from 2.50 in. mandrel-bent stainless steel tubing with integrated spun-body catalytic converters, the 24151 features a single laser fusion weld design and OEM-matched O2 sensor ports to keep the check engine light off. The ceramic substrate with elevated precious metal loading meets Federal EPA emissions standards. Made in the USA and backed by a 5-year/50,000-mile warranty, this H-pipe is ideal for Mustang GT owners seeking a performance-oriented, emissions-legal mid-pipe upgrade.
