All of this work is exhausting!

I had some more welding done on my catalytic converter heat shield.  These welds warped a little bit, but I was able to straighten it back out.

Ground and smoothed.  It isn't perfect, but I'm going to use it.  I'm struggling with this super thin Stainless.

I made a plug for the exhaust pipes so I can backpurge the welds.  I made two different sizes - a 2-1/2" ID pipe (for the cat and mufflers) and a smaller section for 2-1/2" OD pipes.  It seals into the tube with an o-ring, and has a barb fitting on the other side.  I didn't do a lot of research on back purge setups, so hopefully this works and doesn't give me much trouble.

I took a break for a late summer bonfire at a friend's house.  I wish I was a better photographer.

  1. Are you worried about the heat from the weld burning up the o-ring? I have no idea about backpurging exhausts just thinking out loud.
