I think it'd be great to set up a database of of performance parts manufacturers or retailers. Unfortunately there aren't many. I do hope that some site such as this ight manage to collect enough cadillac fans tht we will be able t approach manufacturers and request specific products. Lets get to work.
edit: If you ned someone to harrass, call up Domestic Performance and tell them to get to work on those high flow exhaust headers they told me about a year ago. They never did develope them, although it seems they had the plans and equipment all set up. I don't think thre was enough interest at the time. Maybe that has changed (I hope).
