lot of pipes will work well if you take the time to set the boat up. 3 that will work very well are a Hot pipe, the Monster pipe that CC racing is now selling and if you can get your hands on one, the Beast pipe that CC was selling prior to it, I have one in my sport hydro with a CC 29.5 Monster engine and it pulls real hard with it. at about 1/2 up the straight away end it almost seems like it hits passing gear.
