Borla Cat-Back Exhaust System - S-Type - Polished Tips (2015 - 2017 Mustang GT) 140590

Borla 2.5" S-Type Cat-Back Exhaust (140590) – 2015-2017 Mustang GT & 2024 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.
