I have my header off and cut out the cat. I'm going to wrap from the header all the way up to the mufflers on my 2 bros exhaust. Would it be better to get 1 inch wide wrap or 2 inch? I'm thinking 2 inch. Does anyone know how many feet I will need to do this? I want to put my order in soon. The wrap I'm ordering is black, so it won't bad at all.
