      (2)   No person shall use a muffler cutout, by-pass, straight pipe or similar device upon a motor vehicle on a street, highway or other public way within the City. Any person who violates this subsection (a)(2) shall be subject to a fine of $500.00 for each offense. Each day that a violation continues shall constitute a separate and distinct offense.
      (3)   No person shall operate any motor vehicle on any public way with any exhaust system or exhaust system component that is not labeled in accordance with Sections 205.158 and 205.169 of Title 40 of the Code of Federal Regulations, indicating that the exhaust system or exhaust system component meets the applicable federal noise emission requirements.
