Product Description

The Borla 140585 is an ATAK Cat-Back exhaust for the 2015-2023 Ford Mustang EcoBoost 2.3L Turbo in Coupe configuration. It does not fit Convertible models or vehicles equipped with the Active Valve Exhaust System (4-tip factory exhaust). ATAK is Borla's highest-output muffler technology -- the most aggressive sound level in the Borla lineup -- delivering the loudest exhaust note while eliminating in-cabin drone through acoustically tuned core geometry.

Borla's patented straight-through multi-core muffler design reduces backpressure while absorbing sound waves without disrupting the power pulses that generate torque and horsepower -- unlike chambered mufflers, which use baffles that restrict flow to control sound. The system runs 2.25" T-304 austenitic stainless steel mandrel-bent tubing from the factory connection point to a split rear exit with dual 4" bright chrome round rolled angle-cut tips. CNC precision manufacturing ensures exact fitment with no trimming. 50 state legal. Hand-built in the USA. Backed by Borla's million-mile limited warranty.
