I used the wrap on mine for two reasons, to cover my ugly welds and for the prevention of 3rd degree burns while wearing shorts due to the position of my pipe. The heat through the tape is nowhere near as hot as without it. I can touch it with my leg and it won't burn me.
Thats why I put it on my expansion chamber, so it would not burn my leg cuse I had to put it up side down because of peddle clearence, and it does make the popping of the expansion chamber quiter
