I had Tom Dawson from Dawson Racing Headers custom-make my car's 180-degree headers for a total cost of a little under $3K. Mine were pretty tricky to do since they had to be routed around my racecar's dry sump tank, remote oil filter, axle-mounted alternator and roll cage. Plus, Tom needed to fabricate special flanges to fit my unique 302C heads. I think Tom's total cost for more typical Pantera installations - including construction, coating, brackets, mufflers and installation at his facility in Nuevo, CA - should run well under $2500. I can send digital pictures of my car's headers next week if anyone would like to see them.
Tom's a great guy, works fast (!) and the finished product couldn't have been closer to what I'd envisioned if I'd been standing there next to him the whole time.
