Better Flow, More Power. Ford actually did a decent job on the Mustangs catalytic converters, but the stock H-pipe is pretty restrictive. That's where the Heartthrob Straight Pipe Cat-to-Axle X-Pipe Kit comes into play. Featuring a X crossover and 3" free-flowing mandrel-bent piping, this Heartthrob mid-pipe will dramatically improve exhaust flow for more power and sound that you can feel.

Race Car Growl. This free flowing Cat back X-Pipe Kit system for the 2011-2013+ GT Mustang's 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 installation of the   catback  system requires removing the stock exhaust piping from the catalytic converters back to the axle-back, and reuses the factory catalytic converters saving you money. Clamps and instructions are provided.

Versatile Design. The unique design of the Shinoda Catback exhaust kit Includes for  you to install the Flowpack Axle-Back Exhaust Kit You can keep the stock factory mufflers for a mild sound or go with a set of Flowpack mufflers for a wild sound. The choice is up to you.

Durable Construction. Shinoda uses free-flowing 3" diameter CNC mandrel bent aluminized tubing with a merged X crossover and high flow straight pipe design to improve exhaust flow to provide a significant increase in power and sound.
