Borla 2015-2020 Ford Mustang Shelby GT350 5.2L ATAK Cat-Back Exhaust (Uses Factory Valence)

This Borla ATAK Cat-Back Exhaust System (part 140684) fits 2015-2020 Ford Mustang Shelby GT350 5.2L V8 models with automatic or manual transmission, rear-wheel drive, and 2-door coupe body with selectable driving modes. It delivers aggressive exhaust sound through patented straight-through technology and a merge X-pipe for higher exhaust velocity, added horsepower, torque gains, and sharper throttle response. Built from T-304 stainless steel with mandrel bends for maximum flow, it retains factory valence, bezels, and tips while integrating active valves.
