Meisterschaft GT2 exhaust v. GTC (valved)

[cvstar9M3]

I'm debating getting one of these exhausts... I want a loud exhaust but I was thinking a valved option would be great for the times I wanna be quiet around the city (I live in a heavy residential area and have somewhat of a conservative job). So, I was leaning towards the GTC but I sat in an e92 M3 today with the GT2 exhaust (plus a fabspeed x-pipe without resonators). Car was loud, but good loud and around 3-4000 rpm it was as crazy loud as I thought it would be until may be the 6000 rpm and above. All in all, the GT2 sound is sick! And this car had the x-pipe.

The question though is whether the GTC almost as loud as the GT2 or a totally different sound. I saw some people saying that GTC opened is more like the GTS model ( which I don't think is that loud at all). Others have said the GTC is between the GT and GT2 in terms of loudness. So I don't know what to think anymore. and I've researched this topic tons and watch videos but hard to tell from you tube. If you've had experiences of any kind (particular in person) 1 or both GT2 and GTC, I'd love to hear your input. Thanks.
