I can vouch for the quality of your stuff Fin, those mandrel bends are excellent. For anyone who hasn`t seen a mandrel-bent pipe, you don`t get any of the "crimping" of the pipe like you usually do with a pipe-bender, the mandrel-bent pipes are a consistent diameter all through, no reduction in size at all. Good for gas-flow
Stainless steel is easily welded with a normal MIG welder as well, I used standard mild-steel wire, the weld will rust, but not a problem, I painted the welded area where I joined the stainless to a mild-steel flange with heat-proof black paint, it`s outa sight anyway.
Ideal for intercooler projects too

Keep it real.
