Tight Tubes™ Mild Steel Uncoated Racing Exhaust Headers (78500) by Hedman Hedders®. Primary Tubing Diameter: 1.625". Collector Outlet Diameter: 3". Color: Silver. Header Coating: Uncoated. Professional car builders and seasoned gearheads use Hedman’s innovative 4-into-1 TIGHT TUBES™ because the collector tucks the header tubes and hook-ups against the engine block for more component clearance than ordinary street rod hedders.
The larger volume collector design provides exhaust flow that surpasses standard block hugger design headers.
Hedman Hedders®, a prominent header manufacturer for racing and street header marketplaces, started as a one-man shop in 1954. At first the company's products were designed for straightline drag racers. Over time they became highly popular with elite racing engine builders and racers for their outstanding performance and proven reliability. Made to environmental requirements using the latest computer technology, Hedman Hedders headers are guaranteed to outlast any headers you've used before.
