BMW, or Bavarian Motor Works, is known for its luxury and performance cars. Started as an aircraft engine maker, BMW began building cars in 1928-1929. Most models enjoy good fuel efficiency and low emissions. Keeping a properly working catalytic converter will ensure that your BMW continues to minimize air pollution and meet air quality regulations in your area.

Aftermarket Manufacturer
Catalytic converters in the aftermarket are regulated at least in part by the EPA which requires any catalytic converter made after 1986 to comply with the Clean Air Act. New aftermarket converters are required to have a 5 year/50,000 mile warranty on the converter shell and end pipes.
Original Equipment Manufacturer (OEM)
A catalytic converter coming from an OEM such as Ford or, an OEM supplier, are federally licensed entities required to warrant or guarantee their product. Any converter which meets EPA requirements must be properly labeled. Manufacturers of new converters are also required to provide a warranty on the converter shell and end pipes for 5 years or 50,000 miles, whichever comes first, and for 25,000 miles on converter emission performance.
Used Catalytic Converter
Used converters are only required to meet the performance requirements at the time of sale; no additional warranty is required. EPA considers it a violation of the policy to install a used converter from a salvage yard or sell it for reuse unless it has been properly tested and labeled
