Cat-Back Exhaust System Welded

In the last post regarding the exhaust the 3.5” titanium cat-back system was tacked. Since then, Abe has finished approximately 1,242” of titanium welds. I need to decide if I’m going to:

  1. Leave them as is

  2. Remove the alpha case with a Scotch-Brite pad

  3. Remove the alpha case with a Scotch-Brite pad and heat them with a torch to obtain blue/purple colors

Thoughts?
