I agree with your ideas about the exhaust system. One of my future projects will be replacing my muffler with a more eficient one and tucking it up out of the air stream. The stock one hangs down quite a bit. By keeping the exhaust warmer do you mean using the header wraps that they sell for race cars. I have heard that they can contribute to pipe rusting if the pipes are not warmed up very well. (short trips)
