There is a ton of conflicting info on the web about this subject (single vs dual), and a ton of outright BS (one site goes so far as to say that exhaust gas does not flow backwards at all) but I've always understood that a properly designed single is no more or less efficient or powerful than a properly designed dual. It still comes down to balancing flow and velocity with the correct diameter, bends, welds and design.

The way I look at it, lot of what determines the benefits of single vs. dual comes down to the diameter of the piping and the material used. If my theory is correct, a titanium single with 3"/4" main diameter should have better results when compared to a 2.5"/2.75" stainless steel dual exhaust.
When comparing theoretical exhaust designs, there are simply too many lurking variables to really draw a good conclusion. A better question to ask, would be something along the lines of "Is the Amuse R1000 single better than the Amuse RS-Silent in terms of performance?" or "Is the Robispec exhaust better than the F.I. or Stillen ehxaust?"
Just my .02.

Throw a couple of v-banded cats in the middle for daily driving and then replace them with V-banded straight pipes for the track. I think I just made a mess in my pants and I figured out what I'm eventually going to do with my exhaust...

I heard V-band and longtube..
I look forward to reading your journal updates
