Thanks for the feedback everyone. Jory...
I'll hook you up with the stack...you make your magic happen...
I've been toying with the V-band Connection too. This would allow a quick connect and disconnect. However I want to be able to use as much as "stock" items as I can. I'll have to revisit the layout I have, and see if the V-band could be used. We stock several different Marmon flanges and flares...so it could be possible.
I've also thought about using a heat diverter tube in this application too. Only down side to this is that it does not close off 100%.
Feel free to keep adding ideas to this. It can only make it better!!
