Genuine Eberspacher 10351+ 10391 NOS Mercedes muffler for the W110. Multiple parts numbers for the same one. Fits the 220b, 220sb,230,230S +250S.

Of course the original mufflers have not been available for more than a decade and have been replaced by stainless steel which just isn’t the same and sounds different. If you are doing a correct restoration or just want to experience the car as it was built then this is for you.
