James, The headers are out there: they just have to be made for the car on demand, no suppliers stock them. I have a picture I got from the U.K. on them and the name of the company who makes them. They cost 700lb's and not made to fit a car with a catalitic converter. My U.K. friend said it would be better to build in the states for the catalitic converter. I'm working on it. You also have to design headers to function properly. The october 2000 issue of Hot Rod magazine has all the info on exhaust science. When I find a shop that will them right here in Dallas, It will be called ( The Exhaust Fix ) I will advise the group. I would make several sets. Headers will normally increas HP 15 to 20%. There are some other tricks you can do to gas, and air to up the HP right now, but all these things have to work together or you might damage the engine. John Hervey www.specialTauto.com
