KO4 Exhaust/DP Flange

[Sidey]

I had flanges cut by my engineer for Gizmo and I, and Thought I would help you guys out with the drawing if you would like to get the same done.

Out of curiosity what size pipework you making your downpipe out of...... bigger than 76mm I hope. You could get away with 3.5inch 88mm and still have access to the nuts. 3.25inch 83mm would be good and probably the best compromise.
