Product Notes

3 (in) Tube Diameter Dual Split Rear Exit

The MagnaFlow 1999-2004 Ford Mustang Competition Series Cat-Back Performance Exhaust System brings an aggressive, attention-grabbing edge to the deep resonant exhaust note we're so well known for. This exhaust kit is designed to enhance your 4.6L 1999-2004 Ford Mustang with dyno-proven performance made possible thanks to fast-flowing mandrel bent 3in. main piping and 2 Straight-Through mufflers ending in a Dual Split Rear exit with 3in. Polished Clamp-On Single Wall Angle Cut Cut Edge tips featuring a sporty finish. The exhaust system's cat-back layout replaces your ride's exhaust system from near the catalytic converter on back. Exhaust system 16394 is engineered to make your vehicle's engine produce Aggressive exterior and Moderate interior sound levels, befitting its competition-oriented design. 16394's direct-fit design makes installation a breeze thanks to the use of advanced 3D scanning techniques. This performance exhaust system is made of 100% durable and corrosion-resistant stainless steel and produced using CNC precision robotic manufacturing, all backed by MagnaFlow's limited lifetime warranty. Please check to ensure compliance with local noise regulations.
