Flowmaster Introduces 49-State Legal Catalytic Converters

Whether you like it or not, chances are your state requires you to run a catalytic converter on your street car. While most OEM pieces are restrictive to exhaust flow, Flowmaster has just announced a new 49-state legal (sorry California, snake bit again) catalytic converter. They’re OBD compliant, and even come with warranty.

Official Release:

Flowmaster revolutionized performance mufflers with its chambered design and fans wanted more, so it began making complete exhaust systems. Then people demanded affordable stainless steel kits and Flowmaster listened again. Now, for the first time in its 30-year history, Flowmaster is offering street-legal replacement universal fit catalytic converters built not only to meet 49-state USEPA requirements, but exceed them.

Flowmaster 49-state Universal Catalytic Converters are made in the U.S.A. using stainless steel outer shell construction with noble metal loadings on OEM quality grade substrates. The converters are available in a wide variety of Pre-OBD and OBD II EPA universal fit applications while carrying a 25,000-mile internal components emissions warranty and 50,000-mile/5-year warranty on the exterior casing.

The OBD II universal converters have been engineered specifically for maximum efficiency to avoid “MIL” code issues often encountered with the use of low-quality converters. Because the converters carry the Flowmaster name, great care was taken in their development using quality components to ensure they will perform as well as all Flowmaster products.

It’s important to note that while Flowmaster Universal Catalytic Converters meet or exceed USEPA standards in 98-percent of America, they are currently unavailable for sale or use on vehicles licensed or operated in California. For more information, call (707) 544-4761 or visit www.flowmastermufflers.com.
