'76 450SEL exhaust manifold swap..

[76116]

...if I do keep the SEL as MB intended, the integrated manifold/cats have to go...there's a set of non-cat manifolds from an '80 ready to go.   Anyone else done this swap, and what are the exhaust parts (if any) I'll want to complete this change?

..update, after looking at TimeValves info - downpipes post manifold have the same part #.   So, easy swap..

According to the EPC, the downpipes have changed around chassis number 73000 for the 116.032 and 033 types.
Before those, it was two downpipes, and two two-cylinder manifolds on the left side. After, it was one double downpipe and one four-cylinder manifold. These may be interchangeable.

...thanks for checking,  the manifolds I have are one-piece (4-1) and two pieces for the other side..will check the chassis numbers in the meantime.
