Before going Harley I enjoyed a classic british sports car, an MGB.
That's where and when I first heard of exhaust wrap, and what it does - it isn't nice.
Exhaust wrap will trap the heat of the very hot exhaust gases and force them out the exhaust still very hot, in fact much hotter than the factory engineers designed.
The results are :
- excess heat trapped in the head (exhaust valve side) which may result in a warped exhaust valve stem (ouch!) and most certainly in a hot intake port;
- excessive exhaust gas pressure in the muffler;
- excessive operating temperatures in the catalytic converter.
Look at this picture, this is the exhaust clamp securing the downpipe to the head; notice anything ? Cooling fins ?
I don't know why HD heads do not have cooling fins - maybe because the heads themselves are so massive.
Sure thing is, that exhaust wrap is not a good thing for heat dispersion in the head itself.
Mind you, you can always fit a longer heat shield, or even a heat shield to the heat shield !
There are a few key differences between exhaust wrap and heat shields. First, exhaust wrap is made of a material that can withstand high temperatures, while heat shields are typically made of a metal or ceramic material. This means that exhaust wrap will actually help to insulate your exhaust system, while heat shields will only reflect heat away from sensitive components. Another difference is that heat shields are usually attached to the vehicle in some way, while exhaust wrap can simply be wrapped around the exhaust pipe. This makes heat shields a bit more difficult to install, but they will provide a more secure fit. Finally, heat shields will usually be more expensive than exhaust wrap. This is because they are made of more expensive materials and require more labor to install. However, they will last longer and provide better protection than exhaust wrap.
