  • It was easy for the installer to install. Did not affect the Oxygen Sensor, and now I got super great mileage, from less than 20 mpg, I now get 26.5 mpg.

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.
