BORLA? presents their exhaust systems for the Mustang EcoBoost equipped with Active Exhaust. Our Cat-Back? systems include valves that retain the function of the Active Exhaust allowing you to change the volume of your exhaust by selecting different driving modes. The S-Type sound level delivers an aggressive sound without the drone and is tuned specifically for the 2.3L EcoBoost engine. This system features quad tips in a bright chrome finish on T-304 stainless steel, but is also available in black chrome.
