I gather that the latest final word on tuning favors a ~32 inch header

length merging into a 2 into 1 collector and then into a muffler. So, in
the interests of standarization for our bulk buy on spintech mufflers, I
guess that we are looking at a 1 into 1 cruiser muffler and a 2 into 1
collector independant of the muffler. There is a question of having a 2
into one collector built into the muffler, I'll also get clarification on this.

I'm getting a price on a 2 into one merge collector from spintech, and

will keep the group posted. We have about 13 individuals on the bulk buy
list at this time.

Try putting the muffler 11 inches beyond the collector.

Come to think of it Mike the dwg has allowance for casting shrinkage
so don't take the dimensions for the gospel truth. I checked
the actual casting against a six port flange that I have today and it
looks like there will be no problem porting it out for your
hogged out six port.
