WORKHORSE Series – Ford Mustang S550 GT 5.0 Axle-Back Exhaust

The XForce WORKHORSE Series Axle-Back Exhaust for the Ford Mustang S550 GT 5.0 is built for enthusiasts seeking a more aggressive V8 sound paired with long-lasting construction. Made from OEM-grade 409 stainless steel, this system offers strong durability and corrosion resistance while maintaining a clean, purposeful design.

This axle-back configuration replaces the factory rear mufflers and tailpipes, delivering an immediate improvement in sound and appearance. Precision 3D CAD engineering ensures a clean, factory-style bolt-on installation with no cutting or fabrication required.
Sound characteristics are deep and muscular, enhancing the Mustang’s V8 presence at idle and under acceleration. High-quality muffler packing helps preserve tone consistency over time, preventing unwanted changes as the system ages.

Supported by a 5-Year Manufacturer Warranty, with the option to upgrade to a Limited Lifetime Warranty upon registration, the XForce WORKHORSE S550 axle-back provides a well-balanced combination of sound, build quality, and long-term reliability.
