Customer Review: (see review/s)
  • I bought 4 calalytic converters front and back for my Mercedes SL500 and after they were installed by Midas . They made abnormal loud noises at random times. The installation was fine but the converters are not. They sound like the car has serious mechanical problems. I took the car for 2nd opinion and was diagnosed to confirm the converters problem.
