I have to say fitment was PERFECT! And the Titanium Tips compliment my car really well but... as soon as I started driving it I immediately started hearing drone!
If I put the windows down it obviously gets better but I rarely do that, I live in South Florida, 90% humidity year round 
Maybe I need to drive it a little and it'll sound better but I'm really not too excited about it :-/
I'll keep you guys posted if it gets any better... I might look into High-flow cats, we'll see i guess.
Meanwhile here is a pic I took with my phone of the finished install

Hey bud, certainly i disagree with it. HKS is so far the only after market exhaust for 335 e92 that doesn't drone AT ALL. i.e. there is no bassy sound which could create resonating in the cabin. You can hear the exhaust coming outside of the car def so quite when windows up similar to the stock exhaust. I just get mine installed last Friday and I can't love it more. I tried borla, akrapovic and eisenmann on my 335 and HKS is the only one that doesn't bother me. It is girl-friend proofed as she doesn't even notice that I have it on comparing to the stock exhaust.
