I had custom pipes made up for my cammer car last week and while I was inspecting the work I noticed the discoloration of the welds.These pipes are 304 stainless steel and the welds had a brass color to them.The fabricator explained that he used a filler rod that had silicon bronze alloyed with the rod.This created a weld that was somewhat soft and not so brittle so as to crack and leak.I don't know if this is your problem,just food for thought.
