Egt in that removing primary cats as he was speaking of "piggies" drastically reduces exhaust gad temperatures. Nothing implying removal of the sensors themselves. Lower temps= happier and healthier car especially when considering turbo life. Still have egt sensor and watched temps drop 400 degrees in my logs with open pipes!
