Product details
The MagnaFlow NEO Series Cat-Back Mustang GT Performance Exhaust System #19579 is made of premium stainless steel and engineered to produce a modern, aggressive sound utilizing our latest technological innovations and decades of exhaust design experience. #19579 creates an aggressive exterior sound while keeping engine noise to a moderate level inside your Mustang GT. It also features an NDT (No Drone Technology) resonator, which reduces unwanted noises that can otherwise occur at cruising speeds. The 3” main piping of this exhaust kit passes through a Tru-X pipe which facilitates the improved evacuation of exhaust gases, before terminating in a quad rear exit featuring 4” black chrome tips. This Ford Mustang exhaust system will integrate with your muscle car’s Active Valve Performance Exhaust system, allowing you to open and close the bypass valves as you please (required valves sold separately; MagnaFlow Part #: 10805). Like all MagnaFlow exhaust systems, #19579 has been dyno-tested to ensure improved performance over your Mustang’s stock system. The exhaust kit is produced using CNC precision robotic manufacturing and backed by MagnaFlow’s Limited Lifetime Warranty.
