I have yet to see any evidence to back this assertion, despite how many times it's been made. My 135i dynod 278 stock in 100 degree weather, exactly 5hp less than the highest 335i that had ever dynod on that dyno, and that was in 60 degree weather. In other words, indentical. Neither car gains much HP at all from a catback, which should tell you something.
