Nissan 370Z Forum - View Single Post - Rattle at idle / 4K RPM after cat back install? Muffler on evap canister heat shield

Just as the title states, I installed my cat back and sounds amazing! But I had an unwanted rattle. Traced it down to my passenger side muffler canister is sitting on the metal heat shield for the EVAP canister. Exhaust shop threw a piece of rubber between the two pieces and it stopped rattling but it fell out sometime on the interstate last night. So clearly not a long term fix.

My question is, can I remove the heat shield and have clearance? So the muffler won't hit it? Will it get to hot and melt the EVAP canister? I have some of that high heat reflective tape up to like 2000 degrees I could cover the side of the evap canister in. I don't see it getting that hot under there. Or is that heat shield not gonna prove enough clearance? Anyone removed it? Or have another solution?
