Hedman Hot Rodz Engine Swap Headers
Hot rodding has always been about taking two or more parts that were never designed to work together and make then work together seamlessly. It is a never-ending effort to shove as much horsepower and torque under a vehicle's hood as possible. Unfortunately, any project can come to a screeching halt when it comes to bolting up a set of headers.
Hedman Hot Rodz engine swap headers are specifically designed for non-factory engine and vehicle model combinations. Available in mild steel or stainless with 16-gauge header tubes uncoated and coated. The HTC silver and Black Maxx ceramic-metallic coatings offer superior heat insulation and anti-corrosion properties to protect your "Hedder" investment and retain more heat inside the header tubes for increased exhaust velocity and improved scavenging.
