Catalytic Converter Exemption.pdf

The California Air Resources Board (ARB) has granted an exemption to Maremont Corporation for their new aftermarket 3-way and 3-way plus catalytic converters under Vehicle Code Section 27156. The exemption allows for the installation of these converters on specific vehicles, subject to certain conditions. The converters have been tested and meet the requirements of Title 13, California Code of Regulations, Section 2222(h). The exemption is conditional upon no changes being made to the converters without prior approval from the ARB, and marketing of the converters must be done using the approved identification and applications. Any oral or written references to the exemption must include a disclaimer stating that it is not an endorsement or approval of any emissions reduction claims. The ARB may revoke the exemption if any of the conditions are violated.

Key details of the exemption include:

The exemption applies to Maremont Corporation's 3-way and 3-way plus catalytic converters.
The converters are approved for installation on specific vehicles, including those with 3.8L and 5.0L engines.
The converters have been tested and meet the requirements of Title 13, California Code of Regulations, Section 2222(h).
The exemption is conditional upon certain requirements, including no changes being made to the converters without prior approval from the ARB.
* The ARB may revoke the exemption if any of the conditions are violated.

The Maremont catalytic converters consist of honeycomb-type substrates coated with platinum, palladium, and rhodium, and are enclosed in a stainless steel outer shell. The converters are sold with installation instructions and kits, and come with a warranty. The test data submitted by Maremont Corporation shows that the converters meet the required conversion efficiencies for HC, CO, and NOx.

The staff of the California Air Resources Board recommends that the exemption be granted as requested, and that Executive Order No. D-184 be issued to permit the advertisement, sales, and installation of the new aftermarket catalytic converters.
