Hot Rodding has always been about taking two or more parts that were never designed to work together, and make them work together seamlessly. It is a never ending effort to shove as much horsepower and torque under the vehicle’s hood as possible. Today, Hot Rodding is as popular as ever, and with the huge selection of aftermarket performance parts, and a plentiful supply of new crate and rebuilt classic engines, Hot Rodders couldn’t be happier. But, while freedom of choice has Hot Rodders grinning from ear to ear, any project can come to a screeching halt when it comes to bolting a set of headers up and lowering the engine into its final location. Our line of HOT RODZTM Hedders addresses the special needs of Hot Rodders by manufacturing a wide selection of hedders designed specifically for NON-FACTORY Engine and vehicle model combinations. These pages contain all Hedmans hedders that were built specifically for the way your vehicle DIDN’T come from the factory.
