More significantly, its OE collector design helps simplify installation so you spend more time on the road and less time in the garage.
Leveled-Up Aggression. Besides upping the aggression in the performance department, these shorty headers will also give up their exhaust tone. Specifically, these headers will give your ride a definite race car roar that’s sure to make your fellow motorists sweat.
Retains Factory Catalytic Converters. These shorty headers will install right ahead of your Mustang’s factory catalytic converters. This means you get to keep your ride compliant with emissions regulations.
Durable Build Quality. These shorty headers are constructed from high-quality 16-gauge 409 stainless steel pipes with a diameter of 1-7/8 inches for superior durability. Furthermore, these stainless steel pipes are CNC mandrel-bent and expertly TIG welded, increasing rigidity. These steel pipes are then TIG-welded onto precision-cut flanges precision-cut from 3/8-inch thick stainless steel plates, ensuring a tight seal and outstanding strength. Lastly, these header assemblies feature a raw stainless steel finish designed to take on an eye-catching patina over time.
