Interesting take. I have the Akrapovic Evo/MPE too which is a full exhaust with titanium downpipes. Of course I'm bias, but I think it sounds fantastic. The metal type makes just as much difference as any in the sound.
That said, I've hear numerous S63 cars with downpipes and "high flow"/gutted cats. Downpipes alone typically change the entire character of the sound. I heard a downpipe on the same Akra, and it doesn't even sound the same anymore. Too loud and aggressive to me.
The best combo would be a high flow or factory cat with a titanium street exhaust system. That's just my opinion.
