Outer Limits 4x4 Board

liiking at building an exhaust, and will be using 3" mild steel,

now i can only find stainless flex pipes, how do you weld stainless to mild?

much appreciated,

With a Mig using standard mig wire like you would with mild steel but stanless will rust like the mild over the welds.

as long as it only rusts like standard mild will, it wont be a problem i just dont want it fallin apart in the next 2 years or so,
