Without Active Exhaust Fitment on this page is based on the manufacturer’s application data.
ATAK Black Axle-Back, fitment-checked
For 2024-2025 Mustang GTs that do NOT have Active Exhaust. That single option divides Borla's range for this car, and the companion system covers the cars that do have it.
Active Exhaust is the gate. This black-coated ATAK axle-back is listed for the Ford Mustang in GT and GT Premium trim across 2024 to 2025 without the Active Exhaust option, and a separate system covers cars fitted with it. The valved hardware changes what the rear section has to work with. It is an axle-back, so only the section behind the rear axle is replaced. Confirm the option on the build sheet rather than by eye.
