"In conjunction with the BMW M Performance exhaust system Active Sound, vehicles with 18d engines and all 20ds produced before July 2015 are fitted with an additional tailpipe."
Does this imply that 18d and 20ds produced after July 2015 will come with 2 tailpipes from the factory? I noticed on BMW USA website that 328d (our 320d) sedan and wagon both have 2 tailpipes but figured it was a mistake just like before. I just read a review of a new 320d in Europe and it had 2 tailpipes as well.
