05-10 Mustang 4.6/5.4L Outlaw Exhaust Kit

The 05-10 Mustang 4.6/5.4L Outlaw Exhaust Kit from FLOWMASTER is a bolt-on axle-back system designed for Ford Mustang owners who want an aggressive sound and improved exhaust flow without needing a full system replacement. This kit is perfect for enthusiasts looking to upgrade their factory exhaust while keeping stock manifolds and mid-pipe connectivity. It is suitable for both street drivers and weekend warriors.

Constructed from mandrel-bent stainless steel tubing, the system features a 2.5-inch tailpipe diameter and 4-inch black-finished tips that provide durability and visual impact. FLOWMASTER's signature Outlaw muffler technology utilizes a chambered design to reduce backpressure while enhancing scavenging efficiency, allowing the 4.6L and 5.4L engines to breathe more freely and produce a deeper, more muscular exhaust note. The stainless steel construction resists corrosion and thermal stress, ensuring longevity even in demanding driving conditions.

This kit is specifically designed for 2005–2010 Ford Mustang models equipped with 4.6L or 5.4L V8 engines and bolts directly to the factory axles, making installation straightforward for both DIY installers and professional shops. The complete assembly includes all necessary hardware, but some installations may require adjustments for optimal fit. Weighing 19 pounds, this exhaust kit is a robust upgrade for any Mustang enthusiast.
