Ernst muffler 95 E320 wagon

[kidMoBile]

I ordered a replacement muffler from parts.mbz.org (Rusty); his online catalog described the part as being supplied either from Eberspaecher or from Ansa. Someone on this site voiced their displeasure with Ansa exhaust parts, and I believe Eberspaecher was OEM. It was $30 more than the Ansa. I ordered the Eberspaecher (even doublechecked that it was Eberspaecher specifically with Rusty over the phone), and got a part that was manufactured by Ernst and is painted black. I searched for Ernst in the archives and found nothing. The part is made in Germany at least! Anyone know of this manufacturer and their reputation for exhaust parts? I'm thinking that since I paid for it, I should get the OEM that I requested. Thanks in advance for replies.
