I went up to the Midwest CRCRC on Thursday. The Arrow ran excellent and I was using the 2013 pipe. After trying a few different pipes, the 2013 to me was the best. Offers a totally different powerband. This track however was pretty fast and thursday night I took the engine off in favor for my Nitrotec because I'm not use to that kind of power and I was starting to over drive the car. Definately not the place or time to experiment. Now it's time to learn it.
