Heat protection tape is primarily used to protect against burns.
But especially with 2-stroke exhaust systems it has even a performance-enhancing Effect. Because 2-stroke Exhaust systems are very sensitive to temperature fluctuations. However, the power output is more constant at a constant temperature and can even be higher at higher temperatures.
Often one observes this Effect at the test bench where the first test shows less power than the second or third test with warm/hot exhaust.
This effect can also be observed in a less noticeable way with 4-stroke exhaust systems, but in a weaker form. However, the heat protection band here has an effect on fuel consumption, since less thermal energy has to be applied to heat the catalytic converter.
In addition, it also offers a certain Regarding a small styling factor, since it rusty can hide exhaust pipes.
