Muscle Car Rumble. This free flowing Heartthrob Flowpack Cat-to-Axle H-Pipe Kit for the 2011-2013+ GT Mustang's 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 and mid muffler design.
Reuses Stock Cats. The installation of the Heartthrob Exhaust cat to axle 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 Heartthrob Cat-to-Axle exhaust kit allows you to install the axle-back of your choice. You can keep the stock factory mufflers for a mild sound or go with a set of muffler deletes for a wild sound. The choice is up to you.
Durable Construction. Heartthrob uses free-flowing 3" diameter CNC mandrel bent aluminized tubing with a H style crossover and high flow straight-thru Flowpack mufflers to improve exhaust flow to provide a significant increase in power and sound.
Application. This Heartthrob Flowpack H-Pipe Kit is designed to fit the 2011-2013 GT Mustangs with either the stock factory exhaust manifolds or aftermarket shorty style headers installed.
