Installation

Hedman Hedders® - Standard Duty Racing Exhaust Headers Installation Instructions

Previously used exclusively in the aerospace industry, Hedman Hedders recognized it's potential for improving both the lifespan, and functionality of exhaust headers.

Hedman Stainless Steel Headers use sturdy laser cut 3/8" flanges, and all primary tubes have smooth-flowing mandrel bends.

The factory black paint applied to uncoated headers is not hi-temp, and is for pre-installation protection only. For the ultimate in protection against the elements, Hedman Hedders suggest Hedman's Original HTC coating.

All Hedman street Hedders are MADE IN THE USA, and are backed by a lifetime warranty against manufacturing defects!

Love these headers! Matched them to 781 iron heads and almost gave up on the drivers side, but when you insert them correctly, they fit fine without interfering with the steering box. On the passenger side, it hit the top bolt in the idler arm, so I turned the bolt around and it fit fine! Problem solved.
