Customer Review: (see review/s)
  • This isnt the catalytic converter i needed. I needed the main cat and the post made it seem like this was the right part. Chances are youll be needing the main rear cat so be sure. This isnt the greatest review bc they failed to be descriptive on the part. If your car pulls a code saying your cat needs to be replaced dont buy this. Its just the front pipe.

  • Had to get bolts and nuts to install on the backside of converter. Plus its a inch short. So know the muffler is hitting the heat shield on startup and shutdown.

  • Replaced entire exhaust and this item was part of it. Couple days for shipping arrived undamaged had everything welded and installed and sounds great. This is a fraction of the cost of a direct fit/bolt on converter so was pretty much a no-brainer.

Customer Review: (see review/s)
  • I bought 4 converters front and back for my Mercedes SL500 and was professional installed. The converters make lound noise at random time and speed. Sound like serious mechanical problem to the car. Recheck and confirmed by another mechanical shop for the converters noises.
