N55 3" DP & exhaust.

I was just thinking about DP and exhaust and i am curious as to why a company hasn't made a straight 3" DP to 3 " exhaust for the n55?

Why do u we making these two outlet downpipes and exhaust? I would think a single straight 3" DP alone to a single 3" exhaust to a dual setup will do just fine...
