To all C-Class fans help-

Hi to everyone, I need your help! I’ve been looking for a sports endpot all the time, in which it’s not necessary to rework the rear apron. Unfortunately, this is necessary with Remus, Bosi etc. But it’s also different, I found pictures! Now I hope someone can tell me which manufacturer or type the ESD ́s are on the pictures. I’m grateful for every tip. Exhaust has to be simple, or what do you think about it??? Thanks already.
