Exhaust heat on the oil-pan was created by scotch
For what it's worth;
A few years(?) back while reinstalling the oil pan ( oil screen service) I had reason to think about the significant heat transfer from the massive header collector, to the oil pan. I decided to wrap the collector. 34' of header-wrap (one piece) provided a double layer of insulation. It was so effective that I could touch the wrap without burning my hand. While recently dealing with the D.G. bullshit I was considering doing the same with the new collector but thought it would be criminal to hide all that new shiny chrome. My solution for the new exhaust was a S/S shield. It has 2 layers of header-wrap with a layer of aluminum foil and is retained by 2 C/V boot clamps.
It's discreet and equally affective in preventing the Collector from "cooking" the oil-pan (oil) .
The oil temp. is kept under control in 2 ways. The "shield" and my oil cooler/spin-on adapter ( picture of my previous exhaust system with "wrap".)
Riding the past two years in 38 C. / 100 F. air temps. the oil never went above 75c. / 167F. I had some initial concerns about moisture in the engine and the low oil temp. not being able to evaporate it. That was quickly dispelled and no longer of any concern. To confirm crankcase condensation is being dealt I installed a temporary accumulator between the crankcase vent and my air filter.
It will initially have condensation collect in it but that evaporates quickly once the engine is up to temp. I've never seen any condensation in the "sight-glass".
As I said at the beginning; " For what it's worth? "

Great idea, my ‘79 can get scary hot in hot temps. I’d love to have heard about the DG pipe story. I had one on my first’79. Loved it! Ordered one about 5 years ago, but a beer can was thicker and it was built wrong. DG admitted it. Wish I could find a 6/1 built well and soused good?

Have you considered the stainless steel sports exhaust system made in Finland by Kawasaki1300parts? It is actually six into two, but looks very neat, and I have no doubt that it is beautifully made. I bought a pair of their stainless mufflers of original design a few years ago - not used yet - and they are of the very highest quality.
