    Review & Install Video

    Superior Exhaust Upgrade. The Magnaflow Street Cat-Back Exhaust is designed to deliver a discernible bump in performance and aggression for your Active Exhaust equipped 5.0L Mustang without having to tinker a lot with the assembly. This exhaust delivers improved exhaust flow, in comparison to the factory exhaust, resulting in improved torque and rear horsepower with a deep growl sound that adds an aggressive appeal.

    Greater Power and Performance. Backed by a highly-efficient pipe and a straight through, free-flowing muffler design, the Magnaflow Street Cat-Back Exhaust facilitates efficient airflow compared to stock. It delivers improved performance, and a unique tone on the street and drag strip.

    High Strength Stainless Construction. The Magnaflow Street Cat-Back Exhaust is built from highly durable and strong 3-inch mandrel bent stainless steel T 304 for elongated usable life. It delivers a clear and smooth, yet throaty sound. You will be excited to note that the design utilizes high-quality twin tips which gives good resonance. The tips are completed in a classy polished finish that highlights its appeal and protects the exhaust from wear and corrosion.

    Installation. This Magnaflow Street Cat-Back Exhaust allows for an easy direct bolt-on installation in just under 4 hours. No custom modifications are required for the installation, meaning it should be easy and direct.

    Warranty. Magnaflow provides a limited lifetime warranty against material and workmanship flaws.

    Application. The Magnaflow Street Cat-Back Exhaust is compatible with the 2018-2019 Ford 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).

      New Exhaust

      Not quite as loud as I wanted but sounds great. Nothing obnoxious sounding just a simple rumble with a little throaty idle and cruising sound under small acceleration.
