Hedman Hedders
American-made Hedman Hedders have been helping racers unleash more power since 1954! Every set of headers Hedman makes is mandrel-bent for a consistent internal diameter and maximum flow, then flame-tested against leaks. For easy installation, they have unique ball socket collector flanges, which give you up to 20° of connection flexibility in case your pipes don’t match up perfectly. Hedders come with all the gaskets and hardware you need, plus instructions. All of Hedman’s Street Hedders are warranted for life, while Husler Hedders for racing have a 3-year limited warranty. Hedman also makes mufflers, exhaust tips, tubing, and other exhaust parts to those same high standards of performance and quality.Hedman Hedders, began as a one man shop in 1954. Bob Hedman, founder of Hedman Hedders, sold his highly sought after exhaust tubes to fellow racers on the salt flats of the Mojave Desert. But, what started out as a way to make a few bucks to pay for Bobs racing hobby, quickly turned into the premier header manufacturer for both the racing and street header marketplaces.
Originally designed for straightline drag racers, word spread quickly about Hedmans reputation for building headers that gave you the best boost in power for your dollar. It wasnt long before Hedman Hedders was the brand of choice among racings elite engine builders, racers and race series. Familiar names like Don Garlits, Warren Johnson, Shirley Muldowney, Bob Chandler and his BIG FOOT Race Team, and the IROC series.
Hedman Hedders constantly reshapes itself to meet environmental requirements and incorporates computer technology to ensure that its products offer the best performance improvement.
Whether youre a Pro or sportsman racer, Hedman Hedders builds your headers with one goal in mind, optimum performance. Even if youre not a racer, the lessons Hedman learns at the track and on the dyno, make it into every street header we design.
