The history of Kooks Headers & Exhaust dates back to 1962 when George Kook (Papa Kook) used his gas torch to build his first set of headers for his family's race car. Involved heavily in racing, his talents did not go unnoticed by all the local racers. Papa Kook competed week in and week out at area drag strips. The business of building high-quality race headers and exhaust systems continues to this day. Choose Kooks for a proven bolt-on performance improvement that you can feel and hear.
