Have to drop exhuast when removing heat shield for under passenger seat diesel heater install?

Hello great hive mind,
I am planning on installing a diesel heater under the passenger seat as so many people have also done. I've watched a lot of videos and everyone seems to skim over "just drop the heatshield" during the install videos/documentation.
I was expecting to just find the black plastic pins that you put wood screws into to pop up but found that I dont have those and everything is bolted in in a way that seems I'll also need to drop the exhaust for this procedure however I've never heard anyone mention that during install videos (or I'm maybe not paying enough attention?).

I have attached some pictures and circled the bolts and mounts holding the heat shield and the exhaust up that I believe need removed to get access to drill my hole under the seat and run the heater exhaust and intake hoses, fuel line, ect.. I would love some confirmation that I'm not too crazy here and that letting the exhuast dangle for a bit while I do this install shouldnt hurt anything. I got the van with 19k on it but I'm guessing someone had to drop the heatshield at one point and just bolted it back in since there are not any of the plastic pins holding that part in.
Anyway, thank you for any advice or confirmation on what I have pictured. I'm also happy to get more pictures if needed.

Four bolts towards the middle of the van holding the exhaust and heat shield (the black push pin that is pictured is for a separate part of heatshielding)

The mounting piece of hardware and bolt that is supporting the exhuast and holding in the heatshield. There is another single bolt on the right hand of the picture that is out of view but it looks the same. I couldnt get a pic with both bolts in it from under the van.

This seems to be the whole area that needs dropped. 4 bolts in the back and there are two bolts in the front. Those 6 seem to hold in the heat shield and the exhuast. Am I good to drop this all out while I'm doing the install or are there some precautions I should take with supporting the exhaust while it's unbolted from those mount points?

Thanks in advance! Hope this makes sense.

Five years after we installed the Webasto in the rear, we installed the B2B charger under the seat. I have no idea where we could have put the B2B if the Webasto had been there. Considering that when we built the van, we weren't contemplating either addition, I’d say we got lucky.

So I crawl upon my soapbox again. No matter how simple you think you want your van, or how empty your pocket book is when you begin, when you design, contemplate beyond the present.
