I'm most likely going with AFE.

Potentially Dinan when/if they finally get around to releasing one, as I'm running their intake - x-pipe, and exhaust on my M3 and have been pleased. But they messaged saying they are just now starting development, and there isn't a projected date. (Losing the race there Dinan!)

The factory sound isn't bad, and I'm primarily changing due to the aesthetics of the factory drop-can look at well.

Thus far I haven't really heard a clip of any of those listed above that sounds bad. And I'm pretty sure that there will be several people that choose based on what's available, as most are only in pre-order status.
