MagnaFlow SYS C/B 05-09 Mustang GT 4.6L A/B

If you're looking to give your 2005-2009 Ford Mustang GT a more aggressive sound and a noticeable boost in performance, this Magnaflow Street Series cat-back exhaust system is a solid choice. It's designed to replace your factory exhaust from the catalytic converter back, giving your 4.6L V8 engine that deep, resonant tone Magnaflow is known for, with moderate exterior and mild interior sound levels. This system is engineered to work with your Mustang's specific layout, ensuring a good fit and improved flow.

Built from corrosion-resistant stainless steel, this exhaust system is made to last. The main piping is 2.5 inches in diameter and uses mandrel bends, which means the pipe's diameter stays consistent throughout to allow exhaust gases to flow more freely. This helps your engine breathe better, leading to dyno-proven performance gains. The system features two straight-through mufflers and exits at the rear with dual 4-inch polished stainless steel tips that have a double-wall, angle-cut design, giving your Mustang a sharp look to match its improved sound.

Magnaflow uses CNC precision robotic manufacturing to ensure accuracy and consistency in their exhaust systems. This direct-fit design, developed using extensive 3D scanning, means it should install without major modifications. The system comes with everything you need for the axle-back portion of the exhaust, including the mufflers and polished tips. It's backed by Magnaflow's 1-year limited finish warranty and a limited lifetime construction warranty, so you can be confident in its durability.
