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 2018-2023 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.

Why Drivers Choose FAST of West Chester

I can't recommend this place enough. Being able to trust a shop in the performance world is big. The 2hr drive to get there, is worth knowing the job will be done right. Very happy to have found this shop, to
support my builds going forward.

Donald Wojnar
I recently had the pleasure of working with FAST of West Chester for some performance upgrades on my 2022 WRX, and the experience was nothing short of exceptional. I opted for a Borla S-Type exhaust and Cygnus Coilovers, and the team at FAST nailed the installation, fitment, and setup to a T.

Adam Cranston
The team at FAST are excellence in every way. First, I consulted with Dave on mods for my HPDE track car. He listened and advised me on the best parts & mods to achieve my goals. He was patient & gave me space to research the options presented & worked with me through several changes before we built. Second, the build execution was flawless, proper heat shielding, bracing and poly everywhere. All components worked as advertised.

Bryce Budd
This place has been my go to shop for all things Subaru. From simple service to performance parts and tuning, they have been top notch.

William Brunell
Excellent shop. They installed a Cobb Stage 2 DP and Whiteline Sway bars and end links on my 2013 WRX. The work was done right and clean. The estimate was accurate. They were very knowledgeable, friendly and gave me the straight scoop on exactly what I was getting for the money
and what I needed to get where I want to be with it. I'd recommend them
to any car enthusiast.
