ARH Catalytic Converters
 

Does anyone know if ARH cats (on their long tube header setup) are marked in accordance with the following law?

Any new or used after market catalytic converter installed on a vehicle after December 31, 1987, shall meet and be installed in accordance with specifications established by the Environmental Protection Agency. A catalytic converter so installed shall be identified with a visible, permanent, nondestructible label or stamp which will identify the manufacturer, vehicle application and month and year of manufacture. The label shall be in accordance with the following format:

a. New converters - N/XX/YYYY/ZZZZ

b. Used converters - U/XX/YYYY/ZZZZ

N - New converter designation

U - Used converter designation

XX - Manufacturer code issued by EPA

YYYY - Numerical designation of vehicle application

ZZZZ - Month and year of manufacture (i.e. - 0188 for January, 1988)

The 3 I installed nope never had that info on the CATS. My SLP header\cats came with card in the box stating that.

Apparently they will fab an x-pipe with stamped versions... for a price. But they won't provide data on any already in use.
