Product Description

The Borla 140742 S-Type Cat-Back Exhaust System is a performance-engineered exhaust upgrade tailored for 2018-2023 Ford Mustang GT models equipped with the 5.0L V8 and active valve performance exhaust. Designed to enhance both the sound and flow characteristics of the stock system, this S-Type cat-back delivers a richer, deeper, and more aggressive exhaust note that accentuates the Mustang's naturally aspirated V8 soundtrack. The system retains a performance-friendly tone without excessive drone at cruising speeds, making it suitable for daily driving and spirited use alike.

Constructed from premium T-304 stainless steel with precision mandrel bends and featuring a performance merge X-pipe, the 140742 improves exhaust gas velocity and minimizes backpressure for potentially smoother throttle response. Dual polished 4" round rolled angle-cut tips and a dual split rear exit provide a commanding rear appearance. Installation is direct-bolt-on using existing hangers and mounting points, requiring no cutting or welding. While designed for coupes with active exhaust valves, convertible applications are not recommended due to fitment constraints. This system offers a robust combination of sound, performance, and long-lasting durability for Mustang GT enthusiasts.
