JBA Performance Exhaust, a PerTronix brand, has released new Cat4Ward headers for the 5.0-liter Coyote engine in ’11-’13 Mustang GTs.

Emissions legal, the headers are built with 3/8-inch thick flanges at the cylinder head and come with collectors designed to connect to the factory catalytic convertor pipes. The four-tube design is also made from 16-gauge tubing for durability with 1 ¾-inch primaries for increased mid-range horsepower and torque.

The design accommodates both automatic and manual transmission cars.
