Therefore doing a muffler delete in an turbo muffled F10 M5 wouldn't bother me at all. Just remember that I am a little crazy when it comes to the decibal level on M5's. LOL!

But yes everything you pointed out is very observant and accurate. A lot of what you said has exactly to do with the generation of so much power. That design came out of hundreds of hours of Research & Development and hundreds of dyno tests.

When you want your exhaust system to look pretty, you call Akropovic.

When you want proven power for your M5, you call RPi.
