Product Description

The Borla 140684 ATAK Cat-Back Exhaust System is engineered specifically for the 2015-2020 Ford Mustang Shelby GT350 equipped with the 5.2L V8 engine and selectable driving mode. This high-performance exhaust delivers Borla's most aggressive street-legal sound profile, enhancing the vehicle's powerful engine note and throttle response while preserving the functionality of the factory selectable driving mode. ATAK's acoustically tuned design produces a commanding exhaust tone without excessive distortion or drone, making it ideal for enthusiasts who want pronounced, performance-oriented sound.

Constructed from premium T-304 stainless steel with mandrel-bent 2.75" tubing and a merge X-pipe configuration, the 140684 system improves exhaust flow and maximizes performance over the stock setup. The dual split rear exit delivers a muscular visual presence at the back of the vehicle, while the straight-through muffler reduces backpressure to improve overall exhaust efficiency. Installation is fully bolt-on with factory hangers and mounting points for a seamless fit. This system does **not** include exhaust tips and is designed to use the factory bezel/tips for a clean, integrated look. Backed by Borla's Million-Mile Warranty, the 140684 ATAK exhaust offers Mustang Shelby GT350 owners an aggressive sound upgrade and enhanced driving experience.
