I used 1" tape when I wrapped mine. Someone told me it would allow a tighter wrap in the headpipe bends. I did but it took forever to wrap. Plus it took about 35' per side to complete the wrap back to the start of the muffler (so 2 rolls needed).
Soaked in water to wrap and went out for a ride after I was done to dry it out. Every time I came to a stop I was encased in my own personal fog bank. People kept honking and yelling ,"Hey man, I think your on fire!"
