Improves Exhaust Flow.
Ford actually did a nice job on the stock Catalytic Converters, but the factory H-pipe could actually use some improvement. That's where the Pypes X-Pipe comes into play. Designed to balance out the exhaust gas pressure in your system, this X-pipe reuses the stock Cats saving you money.
Race Car Growl.
This free flowing Pypes X-Pipe for the 2011-2014 GT Mustangs not only increases power, but it also adds a loud raspy, race car growl to the sound of your exhaust with its modern "X" crossover pipe design. Reuses Stock Cats.
The Pypes X-Pipe bolts up directly behind the stock factory catalytic converters with no cutting required saving you time and money. By reusing your stock catalytic converters and stock clamps, you ensure that your Mustang is smog-legal.
Pypes constructs their mid-pipes from 3" diameter free-flowing mandrel bent 409 stainless steel tubing and has a reduction in the rear to hook up to your 2.75" factory cat-back. This mid-pipe features a merged X crossover to increase exhaust flow for a significant improvement in power and sound.
The Pypes X-Pipe is designed to fit the 2011 to 2014 GT Mustangs with either the stock factory exhaust manifolds or aftermarket shorty style headers installed.
