Borla 2.5" S-Type Cat-Back Exhaust (140590) - 2015-2017 Mustang GT
The 5.0L Coyote Mustang is known for its unmistakable V8 soundtrack, and Borla's 2.5 inch S-Type Cat-Back Exhaust amplifies that character with a deeper, more aggressive tone. Designed for 2015-2017 Mustang GT coupe and convertible models - and compatible with the 2024 Mustang GT - this system delivers Borla's signature S-Type sound: bold, sporty, and refined with zero interior drone.
This dual 2.5 inch system features a high-flow Merge X-Pipe to increase exhaust velocity, improve throttle response, and sharpen overall exhaust tone. Borla's patented straight-through multicore muffler design enhances performance while maintaining a clean, crisp sound that's noticeably louder than stock without being overwhelming. Constructed from premium T-304 austenitic stainless steel, it offers superior durability and corrosion resistance. Finished with dual 4 inch bright chrome rolled angle-cut tips, this S-Type system adds a high-performance look to the rear of your Mustang. An optional front muffler/resonator (Borla 60561) can be added for additional sound control. Backed by Borla's Million-Mile Warranty, it's a long-lasting upgrade built for enthusiasts who want aggressive sound with premium quality.
