Improves Power. Add even more horsepower and torque to the rear wheels of your 5.0 Coyote Mustang with a JBA After Cat X-Pipe. The JBA high flow X-pipe significantly improves your GT's exhaust flow to increase overall performance. This JBA X-pipe is designed to be used with JBA's shorty headers or the stock factory manifolds.

Race Car Growl. This free flowing JBA X-pipe for your 2011-2013+ 5.0-powered GT not only increases power, but with its modern "X" crossover pipe design it also adds a crisp, raspy, race car growl to the sound of your exhaust.

Street Or Off-road Use. The JBA GT X-Pipe bolts up directly behind the stock factory catalytic converters with no cutting required making your Mustang 100% smog-legal. Or you can install the included stainless steel "cat delete" downpipes for even more power making your x-pipe perfect for off-road use.

Quality Construction. The After Cat high-flow X pipe is made to last, using durable 3" stainless steel tubing. With its smooth, precise mandrel bents, there are no kinks to rob you of power.

Required Upgrade. This 3" to 3" mid-pipe requires the use of an aftermarket 3" catback exhaust system, as the factory catback is too small at only 2.75".

Application. This JBA high flow After Cat X-pipe is designed to fit the 2011-2014 GT with either the stock factory exhaust manifolds or aftermarket shorty style headers installed. Reuses the stock Catalytic Converters.
