Im comparing it to my M4 Comp with MPE, where i knew instantly where the noises were, at certain rev ranges, but the M5 isnt quite as predictable etc.

The M5 has a much more reserved use of the pops and bangs.
I had the M4 on a custom tune so it would pop at will at any given time but I think the M5 has sensors which detect heat in the exhaust / engine and hold back the pops until a safe temperature has been reached.
I can get the car to pop on on downshift for a say 5 - 6 sets of pops and it will then stop. This tells me that BMW have implemented a safeguard to stop engine exhaust temps getting too high and causing damage.
It is slightly louder when at full throttle, I think it sounds really nice. But in my opinion its still too quiet with the OPF and Cats in.
The next step for me may be a tune and remove the OPF's by replacing it with Remus midpipe.
Its a different route than I took with the M4, with that I left the exhaust totally standard and did a DeCat which sounded great but my friends Remus (catback) always sounded way better.
I'll try get some rolling video soon as I have a day free this week and going to wash the car and go get some shots of the new mods.
