Enhance performance and sound with this stainless steel cat-back system.
The MagnaFlow Ford Mustang Street Series 15671 exhaust system is designed for 1999 to 2004 Ford Mustang models equipped with a 4.6L engine. This cat-back system features a dual exhaust layout with a 2.5 inch pipe diameter, ensuring optimal airflow and performance. The system includes two straight-through mufflers that produce a smooth, deep tone, enhancing the vehicle's overall sound profile while maintaining a moderate exterior and mild interior noise level.
Constructed from 100 percent stainless steel, this exhaust kit is built to withstand the rigors of daily driving and offers long-lasting durability. The mandrel bent piping ensures a smooth exhaust flow, contributing to performance gains in horsepower and torque as verified by dyno testing. The polished mufflers and 3.5 inch single walled angle cut tips provide a sporty appearance that complements the Mustang's design.
Installation is straightforward, thanks to the direct-fit design developed through extensive 3D scanning.
