Here's a photo of the cat installed back on the vehicle after it was TIG welded this morning.


The entire circumference of the top weld bead was re-welded in case it wanted to crack more. Prior to welding the center of the bead where the crack appeared was cut about 1mm in depth to allow better penatration of the new weld and to remove contaminates. Hopefully it will not crack again.

The fellow who did the welding really did not know why it cracked. He said it was a lower quality weld being a MIG weld. He said the TIG weld will have better penatration and should not crack as easily. He also said it looked like it was done on a machine and that it looked like a good weld.

He said maybe it cracked due to vibration, but he really did not know for sure.
