EJ, I am not sure as it turns out these are custom Cat Back units made for the SLK32 but they say they should fit, I will take some pics in the morning and post in the PM. I hope I am doing the right thing in getting the Renntech pulley kit and ECU flash as I think $3450 is a little rich with installation, then add sales tax. I told them to sell it to my son's shop in Ga so they are given me a 15% discount as they would consider him a dealer/shop jobber. I hope this gives me the punch I am looking for, by the way after the chrysler dealer put the new aux water pump in it was like a new car, sweet.
