Cal. Code Regs. tit. 13 § 1052

Current through Register 2025 Notice Reg. No. 2, January 10, 2025

Section 1052 - Certification Procedures

Manufacturers of replacement exhaust systems or parts shall certify compliance with these regulations, including the appropriate exhaust system noise limits specified in Section 1036(d) of this title. Exhaust system manufacturers, suppliers, and sellers shall certify in each catalog or similar listing they issue that the exhaust system or parts listed for sale in California comply with the exhaust system certification regulations. The catalogs or listings shall specify the vehicle models and engine size and type for which the items are certified.

If the exhaust system manufacturer, supplier, or seller has no catalog or similar listing, or if the part becomes available after printing of the listing, the certification may be printed or otherwise labeled on the part or on the container in which the part is sold, or the certification may be placed in the container. Such individual certifications shall specify the vehicle models for which the part is certified.

The certification may be on a form attached to the catalog or listing, identifying the particular listing to which it refers and specifying the systems or parts that are not certified. Noncertified systems may be shown, but they must be clearly represented as not being legal for use on highways in California.

(a) Exhaust System. A complete exhaust system shall be certified as an assembly.

(b) Exhaust System Parts. Mufflers, resonators, chambered pipes, flare tips, taper tips, and other sound-modifying parts shall be certified for use in at least one system when tested with the remaining parts of the vehicle manufacturer's original equipment or an exhaust manufacturer's certified replacement system. Catalytic converters, manifolds, and smooth exhaust and tail pipes are not required to be certified separately.

(c) Special Systems. Special exhaust systems designed for engines modified for high performance or other characteristics that affect exhaust noise shall be certified for at least one engine modification for which it is designed by the manufacturer of the special exhaust system.

(d) Partially Exempt Systems. The catalog or other listing that certifies exhaust systems or parts permitted to produce more than 95 dB(A) under Section 1036(d)(2) of this title shall indicate by words or symbols that the noise is more than 95 dB(A), but no louder than that from the original equipment or factory duplicate system.
