Borla 4 muffler VS Corsa ....drone VS H-pipe?

[Austrian Viper]

I would like to know what´s the reason that the Corsa exhaust doesn´t drone but the Borla exhaust (even the 4 muffler system) does. (In a GTS that is).

I know that the Corsa has that special chamber system in their mufflers, but you really think THAT is the reason for it not droning?

I see the Corsa has a X-pipe in front of the rear mufflers.

Can it be that THIS is the reason it has no or nearly no drone?

Would adding a H-pipe in front of the borla rear mufflers eventually reduce or eliminate the drone, too?

Anyone tried it, yet?

I don´t really like the raspy sound of the Corsa, but if it´s the only exhaust that has nearly no or no drone at all, then I for sure will go with it.....
