DIY Manifold Parts Store?
http://vibrantperformance.com They should have all the parts you need. Or mandrelbentsoultions.com I think is the name. They have everything as well. But for the price you could buy one already made they are so cheap. I went this route for headers on my E46 M3. However the headers are 1200-2400 unless you buy ebay ones. Good luck either way!!
