Description
Enhance your 1999-2004 Ford Mustang with the MagnaFlow Street Series Cat-Back Exhaust System, designed specifically for 3.8L and 3.9L V6 engines. Crafted from durable, corrosion-resistant stainless steel, this system features mandrel-bent 2.5-inch main piping that ensures unrestricted flow and optimal performance. The dual straight-through mufflers with 3-inch polished clamp-on single wall angle cut tips provide a sporty, resonant sound that enhances your Mustang’s character without overwhelming the cabin or exterior noise levels. This exhaust system replaces the stock components from just behind the catalytic converter to the rear, providing a direct-fit installation that can be completed with minimal effort thanks to extensive 3D scanning during development for precise fitment. Designed with CNC robotic manufacturing techniques, the MagnaFlow system guarantees high-quality craftsmanship and durability. It delivers dyno-proven gains in horsepower and torque, making it an ideal upgrade for enthusiasts seeking both sound and performance improvements. Whether you’re aiming for a more aggressive sound or enhanced exhaust flow, this system offers a balanced blend of moderate exterior and mild interior sound levels, ensuring your Mustang stands out at every stoplight.
