I didn't think you were trying to start crap, it's a legitimate question.

I forgot to address your point of X pipes connecting and splitting. When you look at the x pipe in the above pictures, the two pipes connect, but remain two individual pipes. If you're wondering why they connect at all, which a lot of people do, it's to balance the exhaust so it all flows out at the same rate. This is important for a consistent sound and better torque.

But as I already touched on, to me there is a difference between an exhaust going into one pipe and then splitting into two separate pipes, as opposed to two pipes that never combine into a single pipe. I guess I just don't see the difference between 8" of single pipe, or 5'.

Not trying to sound anal, I just don't think a single pipe really meets the spirit of "true dual."
