      Race-Ready Sound. An aggressive boom is the sound of your Active Exhaust equipped 5.0L S550 Mustang when you install the Magnaflow Competition Axle-Back Exhaust system. The larger, 3 inch tube size gives you more power and the sound to match. Give your V8 powered Pony a growl that you can feel when prowling down the track.

      Pick Up the Power. With the larger pipe size comes significant gains in both torque and horsepower. Let your Pony open up by improving exhaust flow with this Competition Axle-Back Exhaust system.

      Rugged, Yet Stylish Construction. Made from mandrel-bent, 409 stainless steel, this exhaust pipe is durable, corrosion-resistant and ready for speed. The 4 inch tips sit on either side, giving you a quad exhaust that makes your Mustang look like the powerful car it is. A black satin finish sets off virtually any paint job from stock options to custom designs.

      Cut and Clamp Installation. Installing the Magnaflow Competition Axle-Back Exhaust system is designed to be easy. Once you modify the stock exhaust system, everything else is a straightforward bolt-on installation process.

      Application. The Magnaflow Competition Axle-Back Exhaust system fits all 2018-2020 Mustang GT models that is equipped with Active Exhaust.

      Please Note. In order for this Magnaflow Exhaust System to function properly on Mustangs equipped with the Factory Active Exhaust Function, you will need to purchase Magnaflow's Active Valve Kit, part# 10805 (sold separately).
