This cat-back exhaust system has a straight through design with no drone and is lighter than its factory counterparts. Borla's 140684 exhaust kit has a full T-304 stainless steel construction with 2-3/4" mandrel bent piping and reuses your Mustang's existing hangers, mounts, tips and electronics.

The assembly features an integral X-pipe that bolts directly into your original catalytic converters to keep your emission 100% compliant. The ATAK mufflers have 2-1/2" outlets to incorporate perfectly into your factory valance. Once you reconnect the OE electronics, you will still be able to select between the different exhaust driving modes.

Borla utilizes their Acoustically Tuned Applied Kinetics (ATAK) technology that is ideal for those that prefer the sound of their exhaust over their stereos. The ATAK mufflers help deliver the highest available decibel levels within Borla's street-legal lineup. And unlike inferior brands that lose significant sound quality at higher volumes, ATAK is tuned like a graphic equalizer to shape and focus sound waves for optimum high-volume output.

*This will not fit any 2015-2020 GT Mustangs.

The factory exhaust is frequently the first item to get replaced in any new or classic Mustang restoration, and rightly so. The increased performance and better sound that you'll get from an aftermarket system usually far exceeds what the factory can offer. The products from Borla Performance Industries are some of the top exhaust systems available for your Mustang.
