Mike dont use the flex pipes. Personaly I find them to be crap as they don't last very long.

As was mentioned earlier the pipes should be 1.5"

I had to go at mine a bit backwards as I couldn't get the headers off my engine. The bolt heads were slightly rusted away and I didn't want to break the thin casting.

I removed the cast elbow from the hull floor and went at it that way. I purchased a 90 degree elbow in 1.5" dia from CDN tire. I cut off the end that had been expanded and then hammered the narrower end of it into the top of the cast elbow. That way the pipe was long enough to reach from the headers to the hull floor. What was left of the original rusted out pipe in teh header was hammered out to allow the cut end of the pipe to be placed into it. After many times in and out to the work bench I finally got the correct lenght and got it installed. It was a very tight fit. I also the hammered back the orginal rusted out pipe to make a tighter fit around the new pipe and for extra security I placed a clamp on it.

The first picture shows the system after removing the crappy flex stuff.
