Kooks Custom Headers

Kooks Headers and Exhaust offers production applications for many late-model domestic automobiles. This means that you can get that “custom” header for your early or late model application for a fraction of the cost and have it shipped right to your door step. There is no other header company in the country that can offer you a header for your gas engine truck, while still building handmade custom race headers that are used in applications making over 3,000 horsepower. They pride ourselves in being the pioneers in the stainless steel header revolution and have become the innovators in the exhaust industry as a whole. Kooks designs, tests, and manufactures it first; then other companies follow.
