Fits 2011-2014 Ford Mustang Base models (V6-3.7L).

The Roush Dual Axle-Back Exhaust system (MPN: 421145) is engineered to provide an aggressive sound profile for the V6 Mustang without the common cabin drone or "boom" associated with aftermarket systems at cruising speeds. Unlike traditional fiberglass-packed mufflers that degrade over time, this system utilizes a unique open-chambered design. This architecture increases airflow and provides a more consistent, uninhibited exhaust note throughout the life of the vehicle.

Constructed for durability and aesthetics, the mufflers and inlet pipes are fabricated from 409 stainless steel. The dual exhaust tips are made from high-grade 304 stainless steel and finished with a specialized chrome flashing process. This specific treatment is designed to resist the cracking and flaking often seen with standard chrome finishes, maintaining a mirror-like appearance under high heat cycles.

  • Open-chambered muffler design for improved airflow and aggressive tone
  • Eliminates in-cockpit exhaust drone at highway speeds
  • 409 stainless steel mufflers and inlet piping for corrosion resistance
  • 304 stainless steel round tips with chrome flash finish
  • Direct bolt-on installation to factory mounting points
  • Manufacturer Part Number: 421145
