With other locations downstream on a recip engine as you would imagine the temps are way different.

I currently do not have my Cummins probed as I'm not towing yet.

So I have no comparison from my perspective.

Great topic and thx!
I tapped my probe just back of center on the side of the exhaust manifold that faces out at you.

I did a Google search and Genos has a good photo of it.

You have to take the front, passenger wheel liner out, and its a reach to work at it, but it can be done pretty easily.

I tried to use a magnet to collect shavings, the stuff that fell in didn't cause any issues.

Just try to pull bit out to clear it more often, especially when you get closer to popping through.

It's pretty thick material, so it will take a sharp drill bit!

I still have my egr installed, so block off plate is not an option
