Another point you are missing is the fact it "is" a quasi-dual exhaust regardless where the Y-split is.
You keep comparing the 2x 2.25" crush bent pipes to a single 2.5" pipe (or stock 2.25") which is incorrect.
His exhaust has a 2.25" stock pipe running to a muffler that splits it into 2 crush bent 2.25" pipes.
2.25" crush bent piping has an effective size around 1.88" at the 90 degree bends.
This would in effect make it smaller in flow area than the stock SVT exhaust which has 2" mandrel bent duals. Also it has the drawbacks stated previously of slowing down the air flow & causing added turbulence by repeatedly decreasing & expanding the pipe size.
