A Word from the Owner

“Our goal is to strive for excellence and manufacture the highest quality performing products in the industry with the latest technology and materials available. In the end, we deliver not just a bunch of tubes welded together, nor an exhaust with a muffler and a shiny tip. We deliver a designed, engineered and manufactured component of over fifty years of dedication and passion into the craftsmanship of what we do, and remember why every Kooks Headers & Exhaust product manufactured is not just a set of headers.”

George Kook Jr
CEO, Kooks Headers & Exhaust
