Anyone know the inside and outside diameter of the tube use for the headers?.
Please.

If anyones interested, 32mm inside with 3mm wall.

I doubt it's 3mm wall all the way along the tube; probably just a thick section at
the top where it's attached to the engine.

indeed... 1-1.2 sounds more like rest of header

Thanks lads, should have put thats what im using.
