After you get the pipes wrapped and the heat wrap set. Drape off the bike entirely and use very high temp barbeque flat black paint and paint the wrap black. The wrap black is black compared to the white but if you want "BLACK" the paint works great. Just make sure to have anything you don't want black spray paint on covered.
I tried Auto Zone, Advance Auto & Pep Boys and they had no clue what I was asking for. Of course these are the same JA's that didn't know what a dwell meter was. A speed shop will have it. When you start the bike the tape will smoke pretty heavily for about 20 minutes.
