December 20, 2007 - The starting point.
Except for a lapse in 1999-00, Mazda used a nice 4-1 header on the North American naturally aspirated cars. Overseas, some models got a long 4-2-1 design. It's actually a reasonable setup, much better than most stock exhaust manifolds.
I'll cut this up and use it for the flange, just as I did on the last header I made. The iceengineworks parts are designed to be fastened to a stub of round tube.
