Hedman | Tight-Tubes Headers For Street Rods/Tri-5s with 283-400

Hedman - Exhaust Header

Description

Hedman Hedders began in 1954 as a one-man operation. Bob Hedman, founder of Hedman Hedders, sold his highly sought-after exhaust pipes to other racers on the salt flats of the Mojave Desert. But what started as a way to earn a few bucks to pay for Bob's racing hobby, quickly became the premier manufacturer of exhaust pipes for both the racing and street markets.

Originally designed for straight-line drag racers, Hedman's reputation for building exhaust pipes that gave you the most horsepower for your money quickly spread. It wasn't long before Hedman Hedders became the brand of choice among elite engine builders, racers, and racing series. Familiar names like Don Garlits, Warren Johnson, Shirley Muldowney, Bob Chandler and his BIG FOOT race team, and the IROC series.

Hedman Hedders is constantly redesigning itself to meet environmental demands and integrating computer technology to ensure its products deliver the ultimate performance enhancement.

Whether you are a professional or athletic racer, Hedman Hedders builds your hedder with one goal in mind, optimum performance. Even if you are not a racer, the lessons Hedman learns on the track and on the dyno are reflected in every street hedder we design.
