I can get bends off someone - for bottle of whiskey. Hi quality steel. Can get in a few sizes but all are 5mm wall thickness. Would 1 1/4inch be ok with that wall thickness (Not sure if 1/14 inch is the OD then you minus off 10mm to get inner diamter? FOr 4AGE Turbo exhaust manifold
I realise this is heavy - but I don't really mind.
I've heard that if you speed up the gases a bit here you can spool up the turbo quicker...don't want to restrict the flow too much though
