    Loud and Sporty Exhaust Note. Hear your Mustang’s true performance potential with the Borla ATAK Axle-Back Exhaust System. You’re guaranteed to hear the extra volume and improved tone thanks to the super aggressive ATAK mufflers, which come with fine-tuned internal perforations to best focus the exhaust gas’s sound waves. The result is a loud and aggressive exhaust note that has minimal distortion.

    Pushes Performance to the Limit. Borla aren’t just known for their race-ready tone. As a matter of fact, this axle-back exhaust system’s free flowing ATAK mufflers greatly improve exhaust gas flow, while also cooling your engine. The result is even more additional horsepower and torque for your Mustang

    Made from 304 Stainless Steel. Exhaust gasses are made up of a toxic mix of carbon monoxide, nitrogen, hydrocarbons, and vapor. Combined exposure over a long span of time can damage your exhaust system from the inside. That’s why this axle-back exhaust system is constructed from aircraft-grade 304 stainless steel. The end result is vastly improved corrosion resistance, as well as fewer signs of wear and tear.

    Direct Bolt-On Installation. For added convenience, Borla’s ATAK Axle-Back Exhaust system is designed for a simple bolt-on installation. It directly attaches to your vehicle’s OE hanger brackets and factory holes, without requiring any major vehicle modifications.

    Application. This Borla Axle-Back Exhaust system with split rear exits will fit 2015-2019 EcoBoost and V6 Convertible Mustangs without the Active Valve Exhaust.

      Absolutely beautiful

      At the beginning I was afraid that it would be too loud. It turned out to have a perfect tone and not loud at all.

      Expensive but you get what you pay for.

      After hours on Youtube listening to V6 exhausts I came to the conclusion that only Borla was going to deliver a good V6 sound. These are loud with a great rasp note under hard acceleration with nearly nothing at lower throttle positions and my wife loves them (her car). There is no drone at all in the convertible and we have 1000 miles on them. The install instructions say 2 hours but, I did them in 1 hour including jacking up the car and tweaking the hangers a bit. They lose one single star on fit and finish because the hangers on the mufflers are slightly crooked so I had to use a pipe wrench to bend them slightly so that they would fit straight in the exhaust cut outs. We get a lot of compliments on these, and going under a bridge is out of this world under hard acceleration.

      Gives the Ecoboost the sound boost it needs

      Obviously the Ecoboost does not have that loud growl of the V8s, but this exhaust makes the Ecoboost sound great. No its not super loud, but its definitely a good sound. This is the most bang for your buck to get the Ecoboost sounding good.
