Was thinking about the exhaust heat problems, especially on the 570, what causes heat, how to reduce heat. Don’t want to get into a session on what causes heat, but what can be done to reduce it. Question #1, do those of you who have installed, or modified the stock exhaust by installing a larger exit pipe on the muffler still have the heat related problems? It’s my thought that the stock muffler on the 570 is severely undersized thereby restricting exhaust flow causing excessive heat. You thoughts or comments appreciated…..
