The clear tubing is vinyl. I use it because if you heat it to bend it, once cooled it holds its shape. It will melt if you put it on the header. Don't do that. The box was a left over made for a boat. It was 316 stainless done with a nasty to work with marine rod. Try something else. The threaded elbows were food grade stainless left over from an install at a restaurant. I think the fire suppression system.

You can using anything for the connection to the exhaust, I would stick to stainless but 304 will do the job. The plastic tubing must be able to bend and not kind as it gets warmer that is what is nice about vinyl it gets hard thru one heat cycle but softens again when warm, but forgets it was straight and only remembers it was curved.

And here I thought it wasn't an issue with our beasts. I get error code 69 all the time. Is this something you guys would recommend doing or just flash the ecu and tune it out?

For a code 69 replace the t-stat or possibly the temp sender. If you are not one for testing just do both otherwise there are many posts on doing the tests and install on the board.

Up to you. All i have shown is it can be done with other benefits. No need to be ripped off on a tune.

I just had this done on my '02 M5, and it was either 37 or 39 hours, not counting the time the part was at the machinist.

physic of hyper-ionization for clean up

Well here is a sample of the CLEAN UP work, (sorry not a BMW, but still clear, what we talking about) -
the technique that was used, calls "PowerCoding" and it's for entire engine, not just for the engine head.

i'm missing how "power coding" does anything to the secondary air passages in the heads of an S62.

That's the point:
by the PowerCoding, there is no need to open and clean any of the modules or parts of the engine.
it's works by "normal" engine run, during the usual operation.

once it done, all is clean, and it was open (like on the pix) with an other reason, - the pix was shoted to show the result -
anyway how exact it works i guess it's to long to write all here .../ or ..?
