Dual or single or...???

[akry]

I am wondering what kind of exhaust does my W140 has(I think it's "true" dual, with dual header, downpipe, mid-pipes, into a single muffler and come out with 2 tail pipes)??

I know that W220 has "true" dual exhaust for sure with two mufflers on each side. But how about W126s?? Or Even E-Class??

I notice that some later model has only single mid-pipe(correct me if I am wrong)?? Though, they still have 2 tail-pipes. However, I saw a '90 300E with dual mid-pipes!!?? What's going on here??

Regards,
Happy Motoring....
