Sometime ago I bought a new MB exhaust system. The exhaust makes a very heavy, too loud and too dark sound that irritates. It is certainly not the original Mercedes Benz W113 ‘60'ties sound.
I have opened the two Mufflers which have been used for 3.000 to 4.000 km.
Middle muffler:
• As you can see in the middle muffler is hardly sound absorbing materials present.
• Next to this it is an absorbing muffler, hardly any “reflection” capabilities, so nearly no low tone damping.
End muffler:
• As you can see the end muffler is not 100% filled with absorbing materials.
• Next to this it is more an absorbing muffler, so no low tone damping.
1) Has someone experience with opening up original MB mufflers, the architecture, the type and amount of absorbing material used?
2) Can we find the reason why these Mufflers are so different from the original ‘60'ties sound?
Thanks Peter

It'll be a brave man that cuts open a new MB muffler!

I love that sound, so no opening from this perspective. The more low sound the better for me.
But it confirms my theory discussed earlier: the fumes may not fully mix inside the mufflers, therefore uneven fuel amount within cylinder groups will show different CO results in lef and right pipe.

I bought an "original MB exhaust" in 1984 from a MB dealer. It was made by "Eberspächer". It had to be welded together on the car. It is still in the vehicle and will need to be replaced.
Come the time, I am willing to cut it apart.

These MB muffles are from Gillet.
Far as I know they ceased production not only for MB but in general.
Maybe I have one of the last.

I understand there is no expertise about original MB mufflers.
I have also contacted MB Classic Parts HQ Stuttgart and asked them if my mufflers look like the original specified (architecture and materials) 1960'ties mufflers.
I keep you posted.
