What would you choose between 530d and audi A6

[@dnvprojects]

I had bad experience with audi,multitronic and s tronic gearboxes are really bad

[@dnvprojects]

This exact video it was just m550i rear mufler with oem cat,no resonator. Later on i install 200cel downpipe, sound intensified a little bit after
