It's 304; I figured after the turbo didn't require 321.

I only weld if there's no one else available , so a guy at work helped me. He didn't use a purge gas since all the welds were accessible, but obviously you'd have to on headers.

Here's a shot my exhaust bracket (pardon my falling off heat shield ). I didn't put any real engineering into it, but my thought was I wanted it to flex with expansion and cornering but but be stiff over bumps. The material is 410SS so it's stronger than a 300 series.
