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

Race Car Growl. This free flowing SR Performance X-Pipe for your 2011-2014 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 SR Performance GT X-Pipe bolts up directly behind the 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. SR Performance manufactures their After Cat high-flow X-Pipe to last using durable 3" stainless steel tubing that steps down to the factory 2.75" diameter. With its smooth, precise mandrel bents, there are no kinks to rob you of power.

Reuses Factory Cat-Back. This 3" to 2.75" SR Performance Mid Pipe can reuse the factory catback exhaust or an aftermarket catback exhaust system with a 2.75" pipe diameter.

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

      Would This Product give a Check Engine Light On Without a tune? Because I don’t have a tune yet in my 2014 5.0 but I wanna make it Louder, I have Axle Backs mufflers tho

      With some custom work, i.e adapters and welding will this fit in a 2014 V6?

      • Unfortunately we are unable to guarantee fitment with the V6 models as this is designed for the 11-14 Mustang GT models.

          Had a tech at my work install it. Was pretty surprised to see that it didn’t come with new clamps. It doesn’t line up with the mid pipes when it’s connected to the cats. Sound improvement was decent.
