Adam's Canadian 13B Rotary 818-SR Build

Keep in mind the movement within the exhaust setup during driving. I have close to 3/4" of clearance around my tip penetration at the bottom corner of the rear bumper and still manage to find fiberglass residue transfer after a spirited drive. Also heat transfer.

I am trying to figure this out also. I don't want a big gap, so I am thinking of getting high temp silicone mat and making a tight fit bushing (cut holes in some cooking pan mats) that i will affix to there inside of the bumper.

This should help hold the tips in place. I have about a 1/4 gap around mine. As far as heat, fiberglass can take a lot. If I notice any issues, I will might make a high temp bezel.

I have 1/4 inch clearance and no contact at all exiting in the lower right corner below the bumper. It's all about the engine and trans mounts. I have Cusco mounts and there it little movement. The stock mounts are like spaghetti. My exhaust pipe isn't very hot at exit (175) but a rotary has a much hotter exhaust
