One would think the PC111's would drop drastically in price due to obsolescence??

Looks interesting, however you'll probably need to fit heat shield to at least 2 of the three free flowing pipes,

I believe that the 3 into 1 configuration has been shown to be the most efficient for producing power and, so far, this exhaust system has been proven to be the best of that design: Carpenter Race Engines - Triumph Rocket III

Somebody, somewhere, sometime might be able to improve on the Carpenter design and results, but I would wager not by very much at all.

I know the backpressure is important.. wouldn't a set of baffles fix that issue?? I was looking at these flexible baffles to maybe keep them from being TOO loud, and to not lose the backpressure.. New Flexible Exhaust Baffles at Cyril Huze Post or the Big City Thunder Thundermonster Baffles..
What say you folks?

Also, I have read somewhere that a slight increase in pipe size might add a much better flow to the exhaust and add some power to the bike. What size is the stock exhaust @ the header and what would be good to move up to?

Those baffles sound like they would be awesome but 10 to 15 db reduction would still be bloody loud, all the same a great Idea If I were going to do it I'd go the 1 3/4 pipe that is already fair bit larger than std.
I could be wrong but I think my header tubes on the Headers Sam made me are 1 5/8 or somewhere there abouts
