There's two reasons bringing the exhaust pipes together is good. 1) when the left and right banks are connected down stream in the exhaust it equalizes the pressure and the motor runs more "even" from left bank of cylinders to right bank of cylinders. 2) This is the main reason, when you take two pipes, with gases flowing through them at a certain velocity, then merge the two pipes together into one, the velocity increases, and this helps "suck" the exhaust out of the engine, increasing power potential. "Back in the day" true duals were considered the best because everything came from the factory with two undersized down pipes from the manifolds slamming into each other (not a good flowing y pipe) into a single, even more undersized, exhaust pipe. Obviously, if you take your truck and take the down pipes from the manifolds and y-pipe them into a single, half inch exhaust pipe, that will not flow well, lol. Technology and availability/ease/affordability of aftermarket thrives nowadays.
