I will be getting my X5M back hopefully this coming week. I had the Dinan exhaust installed instead of buying another stock system from the accident I was in.

I will report back and let everyone know the sound difference. I expect a small change, but as others have mentioned OP most likely catless DPs will give you the biggest change in sound. But then you have to worry about emissions and a CEL light depending on where you live.
