The headers were made by Jack Davis in California . The real reason we ran the headers out the front was because at the time My car was build (it was the first GT car build) NHRA would not let us modify underneath so we just adapted ,now the modify is allowed ,any way I have dynoyed the headers many times and to my delight they are worth about 7hp over any other set that I have tried. I can change trans and convertors really quick also. LOL
