— Why we stock this

This is the Borla part our customers ask for most.

If you want the install done by experienced Mustang techs who run Borla daily, drop the car off in Thousand Oaks. Otherwise, this is a direct bolt-on with clear instructions and clamp reuse from your existing Borla Cat-Back system.
