I used the xt-ultimate. I got one large sheet. And only did the areas where it is hottest, which on EL headers, is directly after the first set of merges and all around the oul filter area. My uppipe was already wrapped. (It was the 3bolt uppipe that came with my old UELs). To do a full set of headers and uppipe i reckon youd need 2 sheets. But it does have measurements so you can work out how much you need.
