The Original Doug's Headers:
Doug's Headers, the most respected name in the header industry since the 60’s, began in 1958 as a small muffler shop in East Los Angeles, California.
The company expanded rapidly into a shop that designed and built innovative headers for muscle cars and many of the sport's top drag racers. Cars with the famous "Headers by Doug" decal were consistently among the top performers in their various classes. Show more...
Doug's Headers was acquired by PerTronix in January of 2005. Doug's Headers are ideal for muscle cars, street rods, and race cars, as well as trucks, SUVs, and motorhomes. With more than 50 years of experience, Doug's Headers is a name you can trust for superior quality and fit. Doug has been elected to five different drag racing halls of fame and is truly a pioneer in the manufacturing of high performance exhaust systems!
