There were two direct fit headers, Edelbrock TES headers and Hooker 2040 headers. Both were direct bolt ins and came with all the emission hookups to be 50 state legal. Sadly both have been out of production for a few years now and fetch high prices. Hedman now makes emission legal long tube headers. Even though they have all tthe emission hookups, they still require some fab work to hook the exhaust up to them.
