Aggressive Muscle Car Sound. Uncork all the aggressive sound that your GT350's flat-plane-crank 5.2-liter Voodoo engine has to offer. As if the driver selectable multi-mode exhaust wasn't loud enough for you already, this Magnaflow Competition Cat-Back features a pair of straight-through mufflers and a free flowing x-pipe to create an exhaust note that will wake your neighbors and the dead.

More Power and Better Performance. A Magnaflow Competition Cat-Back Exhaust not only improves the sound of your Shelby GT350's exhaust, but also improves its power and performance as well. By reducing back pressure and improving exhaust flow, you will see impressive gains in rear wheel horse power and torque.

Compatible with Factory Multi-Mode Exhaust. One of the cool features of the Shelby GT350 is the multi-mode exhaust that allows the driver to select between normal and sport modes. Knowing that this was one feature that GT350 owners could not do without, Magnaflow manufactures their mufflers with the same butterfly valves as Ford. When closed, the valve blocks the exhaust flow, forcing it out one tip of the muffler to produce a more street friendly sound. When opened, the valve "uncorks" the exhaust flow allowing it to exit through both tips of the muffler to produce an aggressive, throaty race style exhaust note. This Magnaflow Cat-Back reuses the factory valve motors.

Magnaflow Quality. Magnaflow manufactures their Cat-Back Exhaust systems right here in the USA with pride. Magnaflow Competition Cat-Back's are mandrel-bent from 3" diameter, premium grade, 409 stainless steel tubing for outstanding exhaust flow and enduring corrosion resistance. This system includes an X-Pipe and two high flow, straight-through competition mufflers. The mufflers feature a pair of carbon fiber dual 4" tips that replace the faux factory tips located in the rear valance.

Direct Bolt-On Upgrade. Magnaflow's Competition Cat-Back Exhaust with X-Pipe bolts straight up in the stock location with no cutting or extra modifications required. Installation of this Magnaflow Cat-Back can be completed in about two hours with just basic hand tools.

Application. This Magnaflow Competition Cat-Back Exhaust with X-Pipe is designed to fit the 2015-2017 Shelby GT350 and GT350R Mustangs equipped with the Voodoo 5.2L V8 engine. Will not fit GT models.

    Not Good

    The echaust is not syncing with my car and wont let me switch modes, or open the echaust how it is supposed to work. I am still working with Magnaflow to see if there is a way they know how to fix it, because they said that this has never happened to anyone else.
