Borla S-Type 2.5in Axle-Back Exhaust with Valves for 2018-2023 Ford Mustang GT/Bullitt/Mach 1 (5.0L) - 11951

Fits 2018-2023 Ford Mustang GT, GT Premium, Bullitt, and Mach 1 models (5.0L) equipped with the factory Active Valve Performance Exhaust option.

The Borla S-Type axle-back exhaust system (11951) is engineered to enhance the 5.0L Coyote V8's acoustic profile while maintaining full compatibility with the factory active exhaust valves. This rear-section system features 2.5-inch diameter T-304 stainless steel piping, a material choice that offers superior corrosion resistance compared to T-400 series alternatives. The "S-Type" mufflers utilize Borla's patented straight-through and multi-core technology to optimize exhaust velocity and flow without the drone associated with lesser designs.

Precision manufactured via computer-controlled CNC and featuring ultra-smooth mandrel bends, this system ensures a direct-fit installation on both coupe and convertible chassis. The exit is finished with dual bright chrome tips, providing a high-luster aesthetic that complements the Mustang's rear valence.
