Header/Test Pipe Coating/Blanket Help

Hello all.

Just purchased some Nouvalari headers, test pipe and supersport exhaust, and Y pipe. I'd love to get everyone's latest opinion on reducing heat back there. I've heard about zircotec coating as well. Plan is to coat and or use heat blankets on the headers and was wondering if i should do something with the test pipes and Y pipe as well. Thank you in advance!
