Not much beyond a passing consideration TBH. I’m still a ways away from needing to worry about that yet, so I haven’t decided on a final course of action. At least not much beyond being able to say it will definitely get something, just not sure exactly what yet.
I will say tho, that the heat concern is a lot less now that the tailpipes stay underneath the floor and no longer pass through those goofy tubes I had originally thought to go with. In all reality the exhaust system isn’t much different than a regular one, the biggest concern now is the location of the mufflers behind the seats. This is likely where I’ll have to concentrate most of my attention to heat and noise management.
As for where the tailpipes pass through the body, I just might wrap a narrow section of titanium header wrap around the pipes in the middle of the pass-through, not for heat concerns, but rather just in case the pipes move in the openings a bit. The titanium fabric should keep the metal components from banging and rattling.
