Borla S-Type Cat-Back Exhaust (140745CF) - 2018-2023 Mustang GT w/o Active Exhaust
Transform the sound and style of your Mustang GT with the Borla S-Type Cat-Back Exhaust System featuring carbon fiber tips. Designed for 2018-2023 Ford Mustang GT models WITHOUT Active Valve Exhaust, this 3 inch high-flow system delivers Borla's signature S-Type tone - aggressive, crisp, and refined - all while maintaining a drone-free driving experience. It is the perfect upgrade for drivers who want a deeper, more performance-focused exhaust note without the complexity of active valve control.
The Borla 140745CF system includes a Merge X-Pipe for improved exhaust scavenging and smoother tone transition. It also includes adapters for installation on the stock exhaust but should not be used when running full 3 inch inlets. The system exits through dual 4 inch carbon fiber rolled-edge tips with bright centers, giving the rear of the Mustang a premium motorsport-inspired finish. Built with straight-through multi-core technology, mandrel-bent tubing, and CNC precision, this system maximizes performance, durability, and fitment. Backed by Borla's million-mile warranty, it is a long-lasting upgrade for any Mustang GT enthusiast.
