fast warm up ideas: Exhaust heat exchanger

The best way to pump coolant through the cooler is something called "counter flow", which is opposite of what I showed.
You want the exhaust and coolant or water flowing against each other.

Only issue here is that the exhaust gas will not want to flow through the restrictive EGR cooler instead of the open pipe. You will need a restriction in the main pipe to force the flow where you want it.

I had a plan of wrapping copper piping around the long pipe just after the cat

Google "Lexus exhaust heat recovery"

How is a stainless steel Coolant to exhaust EGR cooler not purpose built to exchange heat between the exhaust and coolant. When that's the only thing it does?
I actually don't have a heat exchanger application for this. I was just sharing an idea.
My only application for diesel EGR coolers is reselling them for massive profit.

Or something like this:

I have some more EGR coolers.
Ford 6.0 exhaust cooler like always and something that looks like it came from a John deere. Definitely came out of a big displacement medium to heavy duty diesel engine.
Big enough it could be used as an intake heater or after cooler for a 4cyl car.

I got some 6.4 ford EGR coolers with hardware and hoses.

How much for two of them, shipped to 52405?

Let me get to the UPS shipping hub when they open at 1500 mountain time.
You just want a horizontal and a vertical EGR cooler correct?
Do you want a set with mounting hardware?
I'm assuming they are not for a 6.4L powerstroke.

Actually, I'd like to have two horizontal EGR coolers. The vertical ones appear to have some sort of flex coupling thingy that I don't want to have. I would like mounting hardware and hoses, if you got them, but that's not strictly necessary.

Yes I have 2 horizontal ones.
2 horizontal ones will make the box about 3 to 4 inches shorter.

For my 8L big block Chevy build I am strongly considering using one or 2 to get that pig up to temperature.
