3 Series F30 shape, 320d signal or twin exhausts?

[Joe..]

One for PH as its bugging me…

I regularly see the same shape (F30’s) with twin and single exhausts? What's the different in spec? I don't believe they are X drive, as they usually sit a lot higher.

Think it is a face lift thing, newer ones have the smaller twin pipes (30\35\40i & Ds get larger diameter pipes I think)

Not sure there’s an easy answer
From what I’ve seen :-

Six cylinder petrols 335i , then at facelift (LCI) 340 had split tailpipes.

6 cylinder diesels had the two tail pipes together both pre and post facelift.

I’m sure that 4 cylinders , certainly the popular 320d had a single tail pipe pre LCI and two afterwards.

But I think to really confuse things , the more powerful 4 cylinder petrols (328 , latterly 330) always had two tail pipes together?

As for the remaining 4 cylinder models , 320i and anything thing lower (diesel or petrol) whether they changed to two tail pipes I dunno.

I guess if you’re really bugged you can go to BMW approved used site and look up examples.

LCI was circa 2015.

Nope, still can't find the answer - 2 x 320d M Sports, 65 plate, one with twin, other single...

65 was in facelift year, of 2015, do you know the registration/s to get VIN to get build date?

It's always possible that one was built pre-facelift production and registered post facelift. I've seen many months between build date and reg' date on BMWs.

• edit, to say a very quick look on autotrader, for 2015, found the mix of tailpipes on 65 plates. I didn't find the mix on 15 plate cars or the odd 64.

Seems LCI from August 2015, so definitely much closer to 65 plate 1 sept.

Isn't the twin pipe an option or spec thing on the 4pots?
