X'ed the shop is:
http://www.hytechexhaust.com/. The owner is John just give him a call to set everything up. It has been awhile since I talked with him about the project. It fell through when the last car I had arranged for him pulled out at the last minute. The first session should last a couple of hours during which they will take all the measurements and calculate whether or not the gains will be worth building the headers or not. If it is they will go ahead and quote you price. They will then build the custom mounting flanges and be ready for you to bring the car back in a couple of weeks for building the headers.
