[QUOTE="Travis Munday, post: 735053, member: 52914"] Rodger- Yes, but that is not a worry in a stock, low-performance engine like what is in the ST. In higher performance motors, with large valve overlaps, if you flow the exhaust out too fast, you'll draw out much of the incoming intake charge, lean the cylinder, and burn it out. In low heat, low performance, stock motors, header wrap will do nothing. Header wraps are great for protecting something from the heat of the headers, but they are a bad idea to wrap on the hot exhaust. [/QUOTE]
