Vehicles in New York State with EPA certification will require 49 state, non-OEM grade catalytic converters. Emissions tag is often found under the hood, on the strut tower, or the front core support.

8 Year Warranty

Catalytic Converters are emission control devices which are designed to last the life of the vehicle and do not normally require replacement. Furthermore, if the vehicle is properly used and maintained, original converters are covered by the emission control warranty for 8 years or 80,000 miles. Federal law prohibits repair businesses from replacing these devices except under certain limited circumstances.

In order to verify that proper circumstances exist, the owner of the vehicle on which such repairs are made and a facility representative must sign the required statements on the warranty card.


Magnaflow semi-universal catalytic converters do not come with hardware or additional piping, and will most likely require cutting and drilling to install. If that doesn't sound like your idea of a good afternoon, Magnaflow also offers direct-fit catalytic converters, which are require no cutting or welding.
