Well it seems my center resonator mufflers have gone south, I hear a leak and it is coming from around there. So I ordered a new part from Phil, and it arrived today.

So then as I wanted to get this project going, I looked underneath and found that unlike the diagrams in Mercedes's manual the rear muffler pipes and the center muffler pipe are welded together, not clamped on an overlap. This looks suspect - is this factory original, or am I replacing a non-original exhaust?

This is a 1989 560 SEL in the U.S.

I can't see myself undoing a weld and rewelding the old rear muffler. This means I have to buy a rear muffler also?

the system is clamped from factory, are the pipes still made to slide into each other? if so get the seals and clamps then install as factory, if the pipes are just tac welded use the dramel to breake the welds.

Thanks.

I bit the bullet. Separating those mufflers would have been a massive pain (fully welded all around the pipes!) And that effort - to put an old (probably non-oem, otherwise it would not have been welded) muffler on that is at least 10 years old would have been penny wise and pound foolish.

At least my system will be assembled the way it was supposed to be...
