Can anyone recommend a company that would be able to cut exhaust flanges from plate to form the basis of a turbo manifold.

U2U andyw7de. He's got a waterjet cutting company which would have no problem cutting from mild or stainless steel

Edit to take Aluminium off the list (doh!)

I used ML FABCUTS to make my throttle body manifold plate - http://www.mlfabcuts.co.uk/.

I suplied them with a DXF file after designing the plate on 2D CAD. Waterjet cut out of 12mm ali plate, cost me ~£35.

Which TB's are they Joshy?

They look like Triumph T595 to me........with one extra slotted in .

They are indeed Triumph Daytona T595 TB's
