F82 sounds best with MPE. No if s and but s about it.

a simple solution to the "S55" sound is just equalizing the pipe length before they merge. The stock downpipes create a difference of 14" in driver/passenger pipe lengths where they merge, correct this and you'll have a better sounding S55.

It's a $450 mod that really all M owners should do...
