Hi all, am trying to get the noise out of my car that I know is in there. Was trying to tinker with the rear box butterflys but have given up on that so want to decat the front section (should have been doing this from the start). I dont want to use the existing pipes encase I want to put it back to stock. Was on with MB today ant to buy new ones and alter them they are looking £800 a side. Have had a request with the usual on line breakers but no joy. Tried the site MSL but they dont list the SLK so if any one can help me that would be great.
