There are 2 things that need to happen in a resiliently supported dry stack exhaust system.
You need to support the weight, and you do that in compression with isolators
And you need to stabilize and support the piping in the stack
You want to attach all these isolators to the stiffest structure you can, like a structural bulkhead or a cabin side. This allows the isolators to perform better.
You can use the isolators you pictured, horizontally in compression to support the weight, and with threaded rod to stabilize. The threaded rod allows the rubber to get away from the hot pipe, and 2 is usually adequate per location, through an 8 ft trunk maybe 2 locations
