The MagnaFlow Street Series Cat-Back Performance Exhaust System 15717 brings out the personality of your 3.8L or 3.9L 1999–2004 Ford Mustang with MagnaFlow’s signature deep, resonant and powerful engine tone along with dyno-proven performance. Engineered to improve exhaust flow and throttle response while maintaining comfort, this system delivers Moderate exterior and Mild interior sound levels.
The system features fast-flowing 2.5-inch mandrel-bent main piping and two Straight-Through mufflers to maximize performance and efficiency. It terminates in a Dual Split Rear exit with 3-inch polished clamp-on single wall angle cut tips, giving your Mustang a sporty and aggressive appearance to match its enhanced sound and performance.
The cat-back layout replaces your vehicle’s factory exhaust components from near the catalytic converter rearward. Extensive 3D scanning during development ensures a precise direct-fit design for easy installation. Manufactured from durable, corrosion-resistant stainless steel using advanced CNC precision robotic techniques, system 15717 is backed by MagnaFlow’s 1-year limited finish warranty and limited lifetime construction warranty.
