I will look into something like the lizard skin as a secondary measure. I have the ACL shield in place above the muffler, although it is mounted 2mm below the floor for an air gap, which leaves about 6-10mm between muffler and heat shield. how far from the floor pan is the top of your muffler??
cheers

I'm still waiting for some of my stuff to come back from the ceramic plating shop. Because my mufflers are only 3 inch thick and that I have to keep the exhaust pipes down below the ERA outriggers from the main frame tube to the rocker panel tube, I believe I have about 1 inch clearance to the floor from memory. Also from memory of my mock up I think the bottom of my mufflers are somewhere around 1/2 inch below the frame rail - I don't have an exact measurement. I think the Lizard Skin on the underside of the floors would be a benefit in your case. LizardSkin® Spray-On Insulation : Lizardskin
