California Vehicle Code 27150

The Fast and Furious franchise has a sixteen-year history in Hollywood filmmaking. The successful series of The Fast and Furious movies has created a trend among drivers who like a car that is super-fast, loud, and stands out in the crowd. Of course, the extensive American tradition of competitive race car driving has influenced the appearance of how drivers prefer the look, speed, and sound of their cars. Speed racing has encouraged motorists to alter the sound of their cars to emulate the sound and appearance of cars used in racing. Motor vehicle alterations are subject to the laws of the state.

Every state has laws that limit the amount of noise that your car can make. Exhaust system alterations cause risks to other motorists who are on the road. Other exhaust system alterations cause motorists to be distracted while driving. While most drivers choose cars that please the eye as well as personalities, it is best to make sure that your car meet the guidelines if you decide to modify the car in any way. When driving a vehicle, we need to make sure that the sound is satisfactory according to California’s exhaust system laws.

Be aware of what can happen when you alter the exhaust system on your car. California regulation mandates that vehicles avoid excessive noise and leaks that pollute the environment with toxic gases and carbon monoxide. The state also limits the operation of passenger vehicles other than a truck with a Gross Vehicle Weight Rating (GVWR) less than 6,000 pounds or a motorcycle. A California car’s exhaust noise cannot be greater than 95 decibels, if tested under specific conditions.

Routinely checking your car for leaks, increase or change in noise level, a dangerous apparent smell, and unsecure parts can prevent costly maintenance and the possibility of a citation for a loud exhaust system. If you find yourself noticing that your exhaust system has a high noise level, it is best to correct the problem right away. Delaying could cause you substantial financial hardships. A defective exhaust system not only harms the ecosystem, it also affects other motorists.
