^I was wondering this too. I'm not an exhaust guru, but I would think true dual would be from the header.

I also notice how stillen guys respond on the forums and make changes due to feedback it's good stuff, shows they care.

EDIT:
Doing some research some people say true dual means has two catalytic converters, two mufflers and two tailpipes. Which doesn't explicitly say one pipe. While others say true dual the pipes are separate the entire length(May come together for space but are split internally). I don't know which one is true. I don't know if it matters or the same gains can be had by either system. They are claiming pretty close to FI numbers on the website but that is clearly one pipe that isn't split internally.
