I think its great that this engine works well with so many different pipes. How many times have you decided to try a new engine only to find out that none of the 12 pipes in your collection will work with it?
Lots of good feedback from racers about how all the different combo's work. The only importance to me is a good crisp snappy bottom end and 10 minute pit stops. If I can get that with 6 different pipe choices, that's just awesome!!
