This customer used our supplied PVC header mockup kit for a one of a kind set of headers without the vehicle ever leaving his location. These Big Block Chevy Headers were fixtured up and them built from an American made 304 stainless that was taken to a mirror finish. The collectors used on this header were built to the customers exact specs with a V-Band flange on the end. Each one of our custom headers is hand build and purge tig welded for a perfect fit on your unique application.
