They claim 25HP for cat back and dp's....
Looks like both banks use a common resonator(crossover)
and go out to mufflers from there, rather than a
discrete system for each side.

of course it's a true dual system
They just share the muffler instead of having a x or h-pipe type collector to equalize pressure between both banks, I bet it works really well.
In fact I'll get to find out, I'm putting one on my car in the next few weeks, although with the downpipes.
