I have an Eisenmann muffler for an SLk320. Was new when I bought it and it was never installed because the car was totaled. I have R171 now and this muffler is sitting in my attic. I bet a nice SLK 320 can use it. I have it listed on Ebay because I am way to busy and would hate to not answer email promptly. Therefore is for grabs. My listing is 130607766295.
