Yeah, read that and have bought a filter ( although its too big, so getting another!)

Is this the only option though??

I guess dpf removal would help but not keen on smoke, but love the sound in the video contained in the thread '335D - DPF Removed + Exhaust + IC + Some stg3 software'

Would an open filter get this sound?? Surely there must be some other options??

Do 335d not have recirculating or dump valves as other turbo cars??
