Specifications
Headers, Tight Tubes Street Rod, Block Hugger, Steel, Silver Ceramic Coated, Chevy, Big Block, Pair
Hedman Tight Tubes offer the lowest profile header collector available. Chosen by professional car builders and seasoned gearheads, with Hedman's innovative 4-into-1 Tight Tubes the collector tucks the header tubes and hook-ups against the engine block for more component clearance than ordinary street rod headers. And, the larger volume collector design provides exhaust flow that surpasses standard block hugging designs. Available in mild steel 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. For tight engine compartments, choose Hedman Tight Tubes—the headers that go where ordinary headers won't.
