2018-2021 Ford Mustang GT 5.0L American Thunder Axle-Back Exhaust System by Flowmaster
The new Flowmaster American Thunder Axle-back exhaust system is for 2018-2021 Ford Mustang GT coupes and convertibles with the 5.0L engine and Factory Active Performance Exhaust Option.
System features include a pair of specially designed Outlaw series mufflers giving you high flow with a moderately aggressive exterior and interior tone when the valves are closed, and an aggressive "wide open" exterior sound level when you open up the valves. Other features include large 3.00-inch mandrel-bent 409S stainless steel tubing for high flow, durability, and longevity. Add to that, a pair of our high-quality valves to accommodate the factory exhaust actuators for when you really want to open up the sound.
The system is finished off with quad 4.00-inch polished 304 stainless steel tips for an aggressive look that demands attention, the same as the exhaust note. Includes all necessary parts, hardware and detailed instructions for an easy installation you can do at home.
