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

Muscle Car Rumble. This free flowing JBA Mid Pipe for your 2011-2013+ 5.0-powered GT not only increases power, but it also adds a deep muscle car rumble to the sound of your exhaust with its classic "H" crossover pipe design.

Street Or Off-road Use. The JBA GT H-Pipe bolts up directly behind the stock 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 h-pipe perfect for off-road use.

Quality Construction. The JBA After Cat high-flow H-Pipe is made to last using durable 3" stainless steel tubing. The tubing is mandrel-bent so 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 H-Pipe is designed to fit the 2011-2014 GT with either the stock exhaust manifolds or aftermarket shorty style headers installed. Reuses the stock Catalytic Converters for smog legal use.

GREAT Product!

Installed this myself on my '12 GT in the garage with jack stands. The hardest part was getting those 1/2" bolts off the front pieces of the stock h-pipe, their upside down! (HINT: Loosen them with a wrench ...

great exhaust note

Price wasn't too bad, had this installed along with magnaflow magnapack mufflers and it sounds absolutely amazing especially once it starts revving up, I recommend this product.

Do jab longtube headers work with these ? I don't want to use an x mid pipe , I'd rather have an h pipe and they don't have a shorty h pipe on the drop down option .

  • The JBA After-Cat H-pipe - 3 in. to 3 in. (11-14 GT) is not designed to work with long tube headers so you would be forced to modify your exhaust to make this work. Because you have long tubes you need to compensate and get a shorter mid-pipe. The only mid-pipe we have to offer that works with the JBA long tubes is that X-pipe you were mentioning.

Work With Roush Axle-Backs ? All I have for exhaust upgrades are my Roush axle-backs.....will this H pipe bolt up directly to these?

  • The JBA After-Cat H-pipe - 3 in. to 3 in. (11-14 GT) will not work with only axle backs. This kit will need a 3" cat back system for the H-pipe to be installed.

    GREAT Product!

    Installed this myself on my '12 GT in the garage with jack stands. The hardest part was getting those 1/2" bolts off the front pieces of the stock h-pipe, their upside down! (HINT: Loosen them with a wrench then use a set of vice grips on the end of the bolt to turn it off) Classic throaty sound, deep yet loud. Hooked them up to my GT500 Axle back with resonators cut (3" pipe in their place) SOUNDS AMAZING! No drone and not overwhelming when cruising on hwy.

    Great product

    Very easy to install. it took me 4hrs to install, not because it didn't fit, but because the catalytic converters nuts all stripped. there is no room really to play with underneath the car.
