Description
Upgrade the rear-end presence and exhaust tone of your 2011–2012 Ford Mustang Shelby GT500 5.4L V8 with this Sport 3.0-inch Axle-Back Exhaust System, engineered to deliver aggressive sound, improved flow, and premium styling.
Designed specifically for the supercharged 5.4L platform, this axle-back system replaces the restrictive factory rear section to enhance exhaust efficiency while maintaining proper backpressure. The result is a deeper, throatier exhaust note with a refined sport tone — aggressive under throttle, controlled during cruising.
Constructed with 3.0-inch mandrel-bent piping, this system maximizes exhaust flow and reduces turbulence for improved performance characteristics. The dual rear exit configuration maintains the factory layout while elevating visual appeal with 4.0-inch Single Pro-Series polished tips, featuring a dual-wall slash-cut design for a bold, high-performance look.
