Thermo-Tec 16850 could be used or for baller status (I was going to use this option then my non-baller wallet said no)
http://www.aclperformance.com.au/prod_heatshield.htm is what you could use as its basically thin metal (and was/still is used to wrap APS headers). It's very expensive though, when I checked into it (my memory sucks) it was pricey as crap along with not knowing how much to order to wrap headers.
