Each noise-modifying part of an exhaust system, such as a muffler, resonator, chambered pipe, extractor, taper tip, or flare tip, shall be permanently marked by molding, stamping, indenting, or etching. Markings are not required on clamps, hangers, fasteners, or on smooth-sided tubing used for connecting sound-modifying parts or extending tailpipes.

(a) Required Markings. Required markings shall be as follows:

(1) The name, initials, or lettered trademark of the manufacturer, supplier, or seller of the exhaust system or part; or a coded numbering or lettering system that shall be different from those of other manufacturers, suppliers, or sellers. The method of deciphering coded markings shall be furnished to the department.

(2) A model number or letter designation, which may differ from the catalog number and shall differ for each type or construction of muffler, resonator, or other noise-modifying part.

(b) Size of Markings. Required markings shall be not less than 0.15 in. (3.8 mm) in height.

(c) Location of Markings. Required identification markings shall be located where they are legible to an installer either directly or with an extension mirror, except for markings on a muffler inlet or outlet or other location that might be covered by a clamp. Markings on parts installed under the vehicle body need to be legible only when the vehicle is on a hoist.

(d) Exemption from Permanent Markings. Certified replacement exhaust systems and parts manufactured prior to the pertinent operative dates shown in Section 1051(a) of this title may have the required markings on paper or other labels on the part or on its container in lieu of being permanently marked on the part.
