I have only owned a BMW for about a year and idk if anyone ever started a discussion or even cared about it but my straight piped f12 650i sounds worlds better than my buddy's $7000-8000 crazy expensive exhaust modded m6 (my opinion). i am sure it has something to do with the s63 manifolds being reversed (even different from the n63 reversed manifolds) to keep pressure for the turbo available but i hate the sound. i was thinking of going to a m6 later on but cant get pass the v10 or v12 sound it makes so i am thinking of doing a engine rebuild with stronger parts and stage 2 or 3 turbos to make about the same power as a modded m6. should be a lot cheaper too. the m6 may sound wonderful to some but i prefer my LOUD AND DEEP BIG BLOCK CHEVY RUMBLE FALLOWED BY THAT TRACTOR TURBO WHISTLE any day
