Incorrect. Please refer to the attached image for the correct name of the two mufflers.

I strongly suggest you follow your own advice to prevent yourself looking like an a-hole again.

Is that why you post so frequently over there?

With such a large amount of weight removed from the center, the rear muffler shouldn't have any issue supporting the entire exhaust system weight.

My pipe is a nearly single-piece from trans-back. Supported only by two rubber rings at the back and again at the trans. Has been fine for years that way. I coated it in 3-4 layers of high temp black paint when I installed it and it has yet to rust at all. It will last forever.

What is everyone referring to when they say resonator?
Did you really mean call me an a-hole? Is your name really Lance?

The forward muffler pair.

You did a pretty good job of that yourself.

Hmm....

Thats a particular style and aragance I recognise....

With regards to the exhaust-system, I havent got a Turbo version, so doubt my input would be meaningful in this discussion--apart to mention that on the N/A W123, its secured by four rubber-rings at the back and attached to the trans near the rear mount with a 'U' bracket, which is attached to a rubber-mounted arm from the trans itself...

We call all the 'boxes' silencers here, we make no differentiation between 'Resonator or muffler--They are all Silencers!

Does a 617-912 powered sedan have a "forward muffler pair" and could you straight pipe it legally?

Ah, I CAN answer That one, being a N/A application!

There is what we call the front-box silencer--although it sits about midway down the vehicle after the trans mount. There is nothing between it and the manifold/downpipe, just a pipe...

From this front-box we go to the rear box with its rubber mounts.

I can see no issues with removing this front-box and piping it, although it May be a little noisier.....
--I believe its a 'straight-through' box, so any gains in performance may be limited

Thanks Alastair. Take Alastair's example. That is GOOD terminology. I did not intend a straight-pipe discussion thread to turn into a pissing contest. All good info, but lets act like adults who all understand what it is that each other is referring to.

I had seen something similar on the web, forget where, maybe here!

Printed a pic and showed the fella replacing my system. He looked at it and said "ok". You see the result.

Post #14 has the sound.

"Evil Monkey" appears to be the several times banned Lance- this is not the only forum he's been banished from. His knowledge of MB is deep, but he cannot remain civil in forums. If he could tone it down quite alot we'd all be better off, but over time he has proven that is not possible.
Anyways, we all learn from each other, and the roum here is a great place to hold that knowledge. In return we should buy parts from the folks that pay for the site in order to keep the forum running.

Actually, the removal of the resonator caused no sound issue. When the shop tried to install a rigid hangar directly above the pipe to the body, the resonance was severe. If they did the right job and actually softly hung the pipe, I'm sure it would have been fine. Or, if they fabbed a bracket to span the entire width of the vehicle and use the resonator attachment points (as some members have done), that also would have been excellent.

So, I disagree with the statement that the simple removal of the resonator will cause excessive drone in the cabin. It might offer a touch of noise at exactly 2000 rpm which I really cannot confirm. But, I can assure you that it would be objectionable to only the most critical of observers. Such people would not be driving diesels because of the fundamental additional noise they present.

My 240D was missing the first muffler/resonator/silencer/whatever else you want to call it. It was like that when I bought it. The entire exhaust system was supported from the rear muffler and the exhaust manifold. I replaced rather a lot of rubber exhaust hangers over the course of the four years I had the car, and I ended up having to replace the exhaust manifold because it cracked between the #3 and #4 cylinders, probably from the weight and vibration from the rest of the exhaust system. That much being said, I didn't think it was excessively loud until the exhaust manifold cracked. I also think the exhaust on an MTVR is a bit too quiet, so I may not be the guy to ask.

Wondering what an MTVR is?http://en.wikipedia.org/wiki/Medium_Tactical_Vehicle_Replacement

I'd kind of like to get more exhaust sound out of my current fleet, but I'm getting this hangup about messing with a perfectly good non-rusted exhaust system. The muffler on my 250 was starting to go when I left the States in March, so it may be ready for a Cherry Bomb or something when I get back.
