Summary
Tulsa requires every motor vehicle to run a working muffler and bans cutouts, bypasses, or exhaust mods that make a car louder than its factory system.
Every motor vehicle shall at all times be equipped with a muffler in good working order and in constant operation to prevent excessive or unusual noise and annoying smoke, and no person shall use a muffler cut-out, by-pass or similar device upon a motor vehicle on any street or highway. No person shall modify the exhaust system of a motor vehicle in any manner which will amplify or increase the noise or sound emitted louder than that emitted by the muffler originally installed on the vehicle.
Full Breakdown
Tulsa Revised Traffic Code Section 721 requires every motor vehicle to be equipped at all times with a muffler in good working order and constant operation, and bans muffler cut-outs, bypasses, or similar devices on any street or highway. The code also separately bars modifying a vehicle's exhaust system in any way that amplifies or increases noise beyond what the factory-installed muffler produced. The rule sits inside the Traffic Code's equipment chapter alongside headlamp, horn, and brake requirements, so it's enforced by police during traffic stops, not through a separate noise permit process.
Violations & Fines
Violating Section 721 is a traffic offense; officers can cite a driver for a defective, removed, bypassed, or modified muffler during any stop, and the vehicle can be ordered off the road until the exhaust is repaired.
