Product Description

The Borla 14139 S-Type Cat-Back Exhaust System is engineered specifically for 1987-1993 Ford Mustang GT models equipped with the 5.0L V8 engine and rear-wheel drive. This premium Cat-Back™ system replaces the factory exhaust from the flange back with mandrel-bent T-304 stainless steel tubing and a split rear exit for a classic performance appearance. Its straight-through muffler design reduces backpressure while delivering an aggressive yet refined exhaust note that enhances both daily driving and spirited performance.

Featuring brushed T-304 stainless steel turn-down tips and Borla's S-Type sound tuning, the 14139 provides a balanced exhaust tone with minimal in-cabin drone and improved throttle response. The bolt-on installation uses precision CNC-manufactured components and includes all necessary mounting hardware. Backed by Borla's Million-Mile Warranty, this exhaust system is a durable performance upgrade that elevates both the sound and style of your Mustang GT through the 1987-1993 model years.
