Exhaust Headers
Hedman Headers offer excellent exhaust flow, reduced back pressure and improved performance. Includes hardware, 3” collector to 2-1/2” exhaust reducer, gaskets and instructions needed for installation. Headers are painted black. Tests have shown a 1.1 second improvement in 0 to 60 second times. Expect up to a 20% increase in horsepower and up to a 10% increase in gas mileage. Call or go online and order yours today!
Increases in fuel efficiency and horsepower are based on a truck operating at factory specifications. Increases may vary according to the condition of your truck and driving habits.
When installing headers it will be necessary to cut the existing exhaust pipes to attach the included exhaust reducers. In most cases, new lead pipes will need to be fabricated. For trucks with power steering, a Power Steering Spacer Kit #36-6023 is needed for proper belt alignment.
