Will a x-pipe make any difference in sound?

Right now I have B&B mufflers, if I were to get a X-pipe would there be a increase in sound?
I know the x-pipe doesn't have any sound resonators or cats on it, so I didn't think there would be an increase in sound.
Any opinions would be great!

I have a 2006 A6 that has an H-pipe from the factory. I added B&B Route 66 axle back system using the stock H-pipe. Then removed the H-pipe and installed an X-pipe from a 2008 Vette. Sound, and the hated drone, stayed the same. No change. Waste of time and money.

Talking of wasting money... I didn't know the '08 already had an X-pipe, so bought the full Stinger cat-back rather than just the mufflers - only realised when I picked up the old H-pipe...and discovered it was an X-pipe! D'oh!

At the point the drivers and passenger pipes meet to form the H the factory H pipe seems to join under the weld. ( 2 into 1 then back out to 2 ) I think this is where you get the gases swirling together and a lot of popping with the factory pipe..
With the Corsa H Pipe where the L and R sides meet to form the H there is a distinct separation the pipes don't merge into one.
Unless of course the factory H pipe is dented in flat - butted side to side then welded. It's hard to be 100% positive without taking out the Reciprocating Saw.

It's only a guess, but I think the sheet metal box type of x-pipe allows more volume for exhaust gas expansion which may result in slightly lower pulse velocity through the mufflers.

Anyone have true dual exhaust on their C6 without a "X" or without an "H" crossover pipe? And is it a deeper "old school sound" ??
