Additionally, this system is significantly lighter than your factory exhaust system to maintain the handling you’ve come to expect. On the installation side of the coin, this exhaust system utilizes the stock exhaust hangars and mounts and comes with all the required hardware and instructions to complete your project.

Please Note: This system is only designed for use with models that are NOT equipped with the Active Exhaust Option from the factory.

Tech Tip: If you happen to think this system is slightly louder than you had hoped or have made other modifications that have increased the volume of your Borla Cat-Back, please see 60661 for a simple bolt-on optional resonator from Borla that can easily make this system have a quieter sound.

*This exhaust system is for 2018-2021 models only. This exhaust will not fit 2015-2017 models regardless of installed valance.

The factory exhaust is frequently the first item to get replaced during any major performance-related restoration project, 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 today!

Order this Borla 140745BC Stainless Steel 3" S-Type Cat-Back Exhaust System with 4" Black Tips for your 2018, 2019, 2020 or 2021 Fastback GT Mustang without the Factory Active Exhaust Option today from CJ Pony Parts.
