I suppose that the Porsche Carrera exhaust system could best be described as true-dual. One exhaust for each bank of cylinders.
Suppose there were a way to create an X-Pipe in the exhaust system thereby equalling the flow rate of both banks of cylinders.
Could this be benefitial?

I honestly don't know the answer to your question (so sorry to waste the bandwidth), but I wouldn't do it. The reason is that the exhaust system's job is not just to flow gases. It's to manage the pulses of exhaust gas. Exhausts are tuned for this, because the way the pulses are managed has a big impact on the power curve (sorta like, if you let them stack up you get more low end torque, and if you move them through the system faster, you lose some of that but get high end power). Anyway, sorry for the lame-*** explanation, but suffice to say that exhausts are not just pipes that get rid of smoke, they're tuned components. So, no being an expert on exhausts, I wouldn't mess with it, especially like that.

The engineers in Stuttgart learned their lessons long ago. You can trace the beneifts of a true dual system back to the 964 and 993. The 964 made 247 hp (250 hp ROW) with a fairly restrictive 2 into 1 exhaust. The 95' 993 increased that number to 272 hp. The major difference in the 95' 993 and the 964 is just the 993 had a true dual exhaust and convertering to a 993 exhaust on a 964 usually nets 20 hp. The 993 got another 13 hp when Porsche changed the intake manifold, heads and cams in 96', but as you can see the exhaust was a much bigger restriction.
