After talking to many fellow e63 owners, meeting up with local owners and listening to their modified exhausts, I decided that secondary cat delete was the best for me. I wasn't looking for an obnoxiously loud sound. I didn't want to ruin that AMG "bark". I didn't want to make it sound like a v8 truck or Mustang (which also counts as a truck). I wanted a sound louder than stock, also across all RPMs so that I didn't have to step on it to impress people on the sidewalks that didn't care about me in the first place.
So secondary cat delete gives me all that. Enough loud to make me giggle, and my wife and neighbors give me angry looks at cold startup. The best part, is the car is more responsive due to the free flow of gasses, and there are burbles on lift-off too, thanks heavens for burbleeees.Oh dear M156... gen Z is gonna be missing so much with electrification.
Have a listen yourself if you're looking for something similar.

If you'd like to compare to other setups, here is the link for you: res delete, res delete + xpipe, short and long tubes, etc.
