My brother has a HPF (V2) system on his 335i. In my opinion, sounds great and has the perfect volume (I prefer louder exhausts). It's pretty damn loud on cold start and does drone quite a bit in 6th gear between 1500-2500rpm, but it's still the exhaust I would choose if I had a 335i. The fit and finish was amazing as well and all the welds looked great. I personally think all the other cat-backs are pretty mellow in terms of volume; the HPF isn't as a refined sound as others but I like it. With a catless downpipe however, the drone might be unbearable and other systems might be preferable.
