Has anyone ever tried running without rear muffler and only cat and or middle resonator?
What would that sound like I wonder ,especially since US m6 muffler NLA . :-k

I know on the B7 we removed cat,has no middle muffler only rear n it did not make any change to sound with the cavernous muffler these cars have.
