I second Famous Bob. I used the titanium wrap (2") in lieu of what I had been using on my dirt bikes (glass fiber). It definitely cuts down on the heat. The Ti smokes for the first few miles so don't be surprised with the smoke. And if you ever wash your TRX700XX, I wouldn't spray directly on to the wrap. My only recommendation is to use stainless steel hose clamps (I used one at the engine exhaust port, and then about every 5 inches up to the muffler) and not the stainless ties that come with some of the Header Heat Wrap Kits.
