    All depends on what your msd system is controlling/feeding etc. Is it setup to turn water on/off to a injection point in your header pipe? or is it controlling the water flow to your stinger (i.e. waterbox end of your pipe)? or other?

    I've assumed when you say you have a factory pipe then you mean a wet pipe i.e. Factory-B or Mod pipe.

    Hi the msd is controlling the water into the header pipe from the water inlet pipe and not to the stinger all that is stamped on the pipe is factory pipe and i don't think it is a b pipe

    OK. In this case, regardless of the style/model of exhaust, your msd controller will be injecting water at low RPM and then turning it off at high RPM. Unfortunately an adjustable flow control valve (FCV) won't work for this. The FCVs are designed to work off water pressure in your pump. They don't allow water to flow through them at low pressure (low rpm) but open as the pressure rises (depending on where you set it). So it'd be working completely opposite to what you need.

    So does that mean I can disconnect it altogether or do I need to buy a new one or a new pipe if I disconnect it what will it do to performance if any it isn't a race ski just to play on flat water

    Depends on your pipe. I'm going to assume you have one of these:

    And I'm also assuming the msd controller feed water (via a solenoid) into a barb thats on the front of the header pipe (facing forwards) just above where it bolts to the exhaust manifold. If thats the case then just disconnect it, replace the barb, with a blank plug, and you should be right to go. You will only loose a smidgen bit of bottom.

    Easiest would be if you could post a quick pic of your exhaust system setup to be double sure.
