The MagnaFlow Street Series Cat-Back Performance Exhaust System #15671 brings out the personality of your 1999-2004 Ford Mustang 4.6L with MagnaFlow’s deep, resonant, and powerful signature exhaust tone, paired with dyno-proven performance. Designed to enhance both sound and appearance, this system delivers a sporty edge while maintaining everyday drivability.
The exhaust system features 2.5-inch mandrel-bent main piping and two straight-through mufflers, terminating in a dual split rear exit with 3.5-inch polished clamp-on single-wall angle cut cut edge tips. The result is a bold exhaust note that perfectly complements the Mustang’s iconic muscle car styling.
With this system installed, your vehicle will produce moderate exterior sound levels and mild interior sound levels, ensuring an engaging yet comfortable driving experience. Exhaust kit #15671 utilizes a cat-back layout, replacing the factory exhaust system from near the catalytic converter rearward.
Extensive 3D scanning during development ensures a direct-fit design for easy do-it-yourself installation. Manufactured using CNC precision robotic manufacturing techniques, this exhaust system is backed by MagnaFlow’s 1-year limited finish warranty and limited lifetime construction warranty.
