Show original supplier description

The Milltek SSXFD416 is a premium cat-back exhaust system engineered as a direct replacement for your Ford Mustang's original exhaust. Available in various configurations, it allows you to tailor your Mustang's exhaust note, from a subtle enhancement to a more aggressive tone. This performance exhaust system features a 70.00mm pipe diameter and is designed with active valves for adjustable sound levels. The system includes the necessary parts for installation, such as an X-pipe, axle pipes, and valved outlet pipes with actuators. Polished GT (round) 115 exhaust tips are included to enhance the vehicle's aesthetics. This cat-back system is specifically designed to fit the Ford Mustang 5.0 V8 Mach 1 (Fastback S550) from 2021-2023 and the Ford Mustang 5.0 V8 Dark Horse (S650 Fastback) from 2024-2027. It requires the OE GT 5.0 rear diffuser for proper installation. Milltek recommends using exhaust assembly paste on slotted joints to prevent leaks and seizing.
