CNT V1 or V2 resonated test pipes?

waahbahbopbop

So I know there are a million and one threads on this type of subject already but I haven't read anything about the newer (V2) CNT test pipe design which may be seen here:

I know people love the ART pipes out-pocket/bottle resonator design but the CNT TP's don't look to be as long and beefy. On top of that the O2 sensor bung isn't extended at all which worries me with a CEL.

I currently have a Topspeed pro1 exhaust and y-pipe that I picked up because of the price... I love the tone of it I would just love some more volume, maybe a bit deeper as well. Still considering Berks HFC but he price of test pipes and sound at WOT is very tempting.

With that in mind, my question is whether anyone can recommend the CNT V2 design over the standard resonated TP design. I would like to minimize rasp and especially drone/rattles as much as possible.
