I wonder if this would help with the amount of heat I get from my bike on hot days. I've never really truly thought about if the heat I feel is coming mainly from the pipe or the engine itself.
It keeps the external temps of the header pipes a good bit cooler. Though ymmv Jet Hott claims a temp drop of 35%. Though there's a lot of speculation on the point, it's said that it'll also make a bit more power as well due to better exhaust scavenging. Last, most of the coatings are more corrosion resistant than the steels used
