321 is a stabilized grade of stainless that was developed to resist cracking in aircraft exhaust systems. It's available in various sizes and radii from Burn's stainless. The correct filler is 347 ... another stabilized grade of stainless. I recommend it for turbo exhaust because of the high temperatures.

Lots of guys are using sch10 pipe for this these days because it's cheap and easy to get hold of. 1.25 and 1.50 size.. The 321 is the right way but the bends are very expensive and like someone already said the correct wire is 347. I have a set of bends for a header in my tool box now that are 321 they came from Burns Stainless. You don't want to kill one in the process they will get your attention when you have to start buying replacements.
