What are the steps in tuning a pipe?

[BombThreat]

I'm always asking people on suggestions on pipe cooling setups. But really I'd like to learn how to setup and be able to tweak them myself. Starting with cooling the motor, pipe, how different parts of the pipe being cooling effect performance. How hot the water should be, the motor, ect...

That way I can try different things and test myself at the lake and be able to really know how to do these things, instead of coming back here and just asking questions without really knowing the reasons behind the answers.

Thanks!

A pipe is tuned to rpm by its length. Normally you must change the physical dementions in order to change its rpm range. Most watercraft pipes inject water inside to keep them cool. The ever popular "B" pipe has cooling water ports at three different locations in the headpipe. The amount and location of cooling water affects the temperature of the exhaust gas. The gas moves fastest when its hot and slower when cooled down. The pipes' tuned length can be changed slightly by changing its internal temp. You will make a lot more power by leaving the pipe at its hottest setting and tuning your pump load to match the pipe.
