This Cat-Back Exhaust system is designed to fit 2018-2021 GT Fastback Mustangs equipped with the factory Active Performance Exhaust Option. With a bolt-on design, this exhaust installs easily to the stock connection point. Borla constructed this exhaust fully from T-304 stainless steel, 3” mandrel bent piping, and features black chrome 4” angle cut rolled quad exhaust tips with the Borla logo embossed on each tip. The straight-through design eliminates drone in the cabin, but still delivers a race-inspired exhaust note that you’re sure to love. This exhaust system is much lighter than the factory cat-back system and utilizes an integral X-pipe. All of the necessary hardware is included and reuses your stock exhaust hangers and mounts.

Please Note: This system is only designed for use with models that are 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.
