The original Exhaust Insulating Wrap was developed by Thermo-Tec over 20 years ago. This black Graphite exhaust wrap will withstand continous heat up to 2000*F, unlike many other brands that are only rated at 1200*F . What this means to you, super high quality wrap that will not break down and fall apart, waisting your hard earned dollars. This is the exact product that is sold elseware for over $70.00..........we are having a spring madness sale on these 50 foot rolls (more than enough to do a set of pipies) for Bikernet fans at $35.00 plus $5 bucks shipping ! Hurry up and order, when we run out of current stock the price will go up.
