ROUSH 2011 V6 Mustang Exhaust

2011_v6_exhaust_round The engineers at ROUSH have pioneered a new design philosophy in exhaust with the 2011 5.0L Mustang Exhaust system (part #421127). Now, they've adapted this system to work as a 2011 V6 Mustang Exhaust.


  • Adds an aggressive sound to the normally stealthy V6
  • Uses 409 stainless steel in the construction of the pipes and mufflers to provide long last durability
  • ROUSH exclusive open-chambered design that provides better flow and will not deteriorate over time unlike the fiberglass roving material used in traditional glass packs which have a tendency to deteriorate which changes the exhaust note
  • Exhaust tips are constructed from 304 stainless steel with a unique chrome flashing process eliminating chrome peeling
  • Installation is quick and easy, and uses all factory hanger locations and pierce points
  • No modifications to the vehicle are necessary
