needing to modify my intake manifold, its already made of mild steel, but i need to alter the angle of the tubes, not sure what angle bends, 90 degree maybe? i can probably make 2 runners out of each one.

anyone got any? ebays turning up stainless steel and all the wrong sizes.

I'll measure again, but i think its 1.9" (49mm is the od of the carbs)

2" anygood?

ah, nice one! they might just do! prices are pretty good too. ebays was something silly like £10-£15 each.
