HI Guys,

I know there have been several threads about treating headers like they are leaking all the time and drianing them. I have staggered 525's in my boat and want to pipe a system that will make it easy/convenient to drain them. Has anybody piped their headers like this.

Any pics would be greatly appreciated.

Thanks, Mark

i pulled all 4 CMI's over the winter and pressure tested them, they are all leak free. I am going to install some small 1/8" pipe thread shut off valves with a man. lever right into the bottom of each 90 degree metal fitting that hooks to the bottom hose on each cmi. it will still require to open hatch and throw a lever, but at least i wont need any tools to drain them.
