05-09 Mustang 4.6L Axle Back Kit

The 05-09 Mustang 4.6L Axle Back Kit from MAGNAFLOW PERF EXHAUST is designed for Mustang enthusiasts looking to enhance their vehicle's performance and sound without the need for a full catback exhaust system. This axle-back kit is perfect for those who want to improve their S197 Mustang's exhaust characteristics while maintaining compliance with factory emissions standards.

Engineered for optimal exhaust flow, this system features mandrel-bent tubing and carefully crafted muffler internals to reduce backpressure and enhance exhaust scavenging. The design allows exhaust gases to exit more freely, improving cylinder breathing and unlocking additional horsepower from the naturally aspirated 4.6L V8 engine, typically yielding gains of 10-15 whp while producing a refined aggressive exhaust tone.

This axle-back kit is compatible with 2005 through 2009 Mustang models equipped with the 4.6L engine, including both GT and base V8 variants. Installation is straightforward, requiring only standard hand tools and basic mechanical skills, with no welding or cutting necessary, making it an ideal choice for DIY enthusiasts looking to upgrade their vehicle.
