Available in a variety of styles

The Hedman name has been synonymous with quality and performance at a fair price for over 50 years. Simply bolting on a set of these headers will increase both engine performance and efficiency. Original style headers are manufactured using 16-gauge steel tubing and feature 1/4" thick flanges at the head and collector. Headers are available in a standard black or Hedman’s HTC coating, a ceramic-metallic formula that protects the headers from extreme temperatures and harsh road elements. These are the perfect choice for any classic street machine. Hedman’s Elite series headers are the top-of-the-line. Constructed with heavy 3/8" flanges and 14-gauge tubing, these headers are built to withstand even the toughest conditions. All Elite series headers also feature Hedman’s HTC coating for additional protection and good looks.
