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 ship right out 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. Kooks designs, tests, and manufacturers it first; then other companies follow. If you want high-quality custom exhaust for your ride, then Kooks is the way to go.
