I got to race my Y6 mono with a Ron Buck modified Zenoah and a Insane Dominator pipe yesterday for the first time and came to the realization that when you flip your boat, and since the pipe has an internal stinger, the only way to get the water out of the pipe is to drain it back through the engine. Probably doesn't hurt anything. Just an observation. The boat ran really well. Need to add weight though to keep it on the water.

The pipe has a drain hole in the stinger (inside the pipe)...just hold it header end up and the water drains out...Check it again!

If for some reason your's doesn't have the drain hole, which I doubt, you can drill a small 1/16\" hole on the outside of the pipe just forward of the stinger weld but you will obviously get a little bit of exhaust leakage.

Thanks Marc, I didn't know that. I like the pipe, it makes the boat go really fast.

No prob. Yes it is a good pipe.
