"One motorcycle racing team that employed the system used a laser-guided thermometer and found that while the exhaust can have an internal temperature of around 150 degrees Centigrade, the outside temperate can be low enough for the exhaust pipe to be removed WITHOUT using gloves."
"Lower temperatures also increase the durability and effectiveness of engine and transmission oils, improve engine cooling and help to protect ancillaries such as starters, regulators, wiring and modern alarm and ignition systems from the degrading affects of excessive heat."
Starting to think about doing this.
