California Loud Exhaust Pipe Laws and Out-of-State Registered Vehicles 101

As you know, if you are part of my Youtube audience, I grew up on drag racing and have raced several modified cars, starting with a modded out 1956 356 A Porsche with a 2.8 Litre, Supercharged VW, and a 911 Turbo look, with a 350 Chevy. I am all about freedom, and so was my dad. He used to drag race on the 22 Freeway, and the local cops came to watch him and his friends race while it was under construction.

If you haven’t heard, there has been a lot of legislative noise over motor vehicle exhaust system laws in the nanny state. Be very afraid if you like mods and have a passenger motor vehicle with loud pipes carrying exhaust gasses. The police in CA have decided excessive or unusual noise from an exhaust intake or muffler is unacceptable.

The problem is, what happens when you are just passing through the state with an adequate muffler for your state, but not okay in California? My research indicates California has no right to require a visitor to change their exhaust, but unless you can take it to the Supreme Court, you may still get stuck paying the fine or having your car impounded.

California’s cash-strapped social justice warriors have found a way for the state to generate millions in fines for vehicles without an effective noise-suppressing system. If the coppers say your motor vehicle muffler makes unnecessary noise, you will often pay a mandatory fine.

This is part of the Canada-like trend sweeping California on generating fines, such as loud motor vehicle fines, that are no longer a correctable violation.

In California, drivers of excessively loud motorcycles, cars, vans, trucks, ATVs, etc., will be fined and unable to waive the charge by correcting the problem.

Timeline of the Law

Let’s examine the law dictating how loud your vehicle’s exhaust can legally be. For vehicles weighing less than 6,000 pounds, the sound cap is 95 decibels. Motorcycles built after 1985 need to keep it under 80 decibels. 

Before 2019, getting caught with an overly loud exhaust in California meant receiving a “fix-it ticket.” This was essentially a promise to correct the issue. Show proof of that fix and pay a small; the more significant fine would be waived. Easy enough, right? 

Well, that changed as of January 1, 2019, when Governor Jerry Brown signed Assembly Exceeding, exceeding noise limits became a “disqualifying condition” for a fix-it ticket. This meant drivers had to both fix the problem and pay the fine.

If you’re cited for an exhaust noise violation, you’re responsible for the fine, even if you fix the issue. 

Bikers and Doppler Effect?

Some motorcyclists advocate for ‘loud pipes save lives,’ but the science behind this is questionable. Due to the Doppler Effect, the loud noise of exhaust pipes is primarily heard after the motorcycle has passed. Most motorcycle accidents occur from the front, making this argument less compelling. Additionally, prolonged exposure to such high noise levels can lead to hearing loss, which could ultimately slow your reaction time. 

Fines and Fees

Suggested Fees

If you’re wondering about the penalties, here’s a quick rundown: 

  • First-time conviction: Base fee of $25, with a total bail/fee of $193. No points will be added to your driver’s license, so it doesn’t count toward suspension.
  • Repeated or severe offenses can result in fines of up to $1,000.

“While modifying your exhaust to get that throaty roar can be tempting, compliance with state laws is crucial. Not only to avoid fines but also to ensure public safety and your own hearing health.” – California Bureau of Automotive Repair

It’s important to note that installing an aftermarket exhaust system isn’t illegal as long as it meets all exhaust and safety regulations. If you get cited for excessive noise, you still have the option to dispute the ticket. You can contact the California Bureau of Automotive Repair (BAR) to obtain a certificate of compliance, proving your exhaust is within legal limits. However, remember that BAR only issues these certificates after a citation has been made, not preemptively. 

You’ll have to pay the fine if your exhaust exceeds the legal noise limits. Nevertheless, staying within the law saves you from hassle and helps keep the roads quieter and safer.

What The Law Dictating Loudness of Vehicle Exhaust Means 

To clarify, the rules about how loud your vehicle’s exhaust is haven’t changed. Cars under 6,000 pounds need to be quieter than 95 decibels, and motorcycles should not exceed 80 decibels. 

Lawnmower sound?

To put it in perspective, 95 decibels is as loud as a power lawnmower or a jackhammer. Prolonged exposure to this level of noise can cause permanent hearing loss. An 80-decibel noise, on the other hand, is comparable to a garbage disposal or an alarm clock at close range—or a freight train from 50 feet away. 

But as it stands, if your exhaust is louder than the law allows, you’re likely stuck with paying those noisy vehicle fines.

CHP Gets To Look?

Under CVC § 2804, a member of the California Highway Patrol, upon reasonable belief that any vehicle is being operated in violation of any provisions of this code or is in such unsafe condition as to endanger any person, may require the driver of the vehicle to stop and submit to an inspection of the car, and its equipment, license plates, and registration card. They do not have permission to search the vehicle’s inside or the trunk without probable cause. However, the engine compartment is fair game to CHP. (Does this violate the 4th? Who has the money to fight it?).

CA Veh Code Section 27156

(a) No person shall operate or leave standing upon a highway a motor vehicle that is a gross polluter, as defined in Section 39032.5 of the Health and Safety Code.

Ref Program Goals, Etc.

At this point, you’ll get a considerable fine, no matter what. They can be around 500 bucks or more. But there is no “fail” and ignore; you must pass or lose the ability to register it for the street. The ref program is designed to stop cars with illegal mods. So you cannot drive the vehicle until the ref signs off that it is corrected. If you don’t REF the vehicle, it could get impounded the next time you are pulled over. You get charged the fees for reffing once. You likely get a few chances to pass based on stuff online. I’ve failed at least twice and only had to pay once.


The ref knows the laws, and they fell into quite a gig. They will understand that an FMIC is perfectly legal for factory turbocharged cars, meaning intercooler piping and FMIC will pass.

However, Your BOV Must Be Stocked and Recirculated


First, your intake needs to be stocked, or you need to carry a CARB EO. Next, the exhaust must be stocked with the last cat, making these cat-backs legal, assuming they meet noise requirements. The REF will measure the sound with a DB meter on a tripod from a certain distance at baseline RPMs. The REF will catch fuel rail mods and aftermarket fuel injectors, and they’ll warn you all vacuum lines and boost control must remain in stock. The ref guys usually explain what must be fixed to pass and whatnot.

Out Of Towner Problems with Ref Cars

The rules are straightforward: once you establish residency in California, you must switch your out-of-state driver’s license. Residency is determined if you have a CA mailing address, pay utilities there, or send and receive mail at that address. So, to keep your out-of-state license and registration, avoid putting your name on any lease agreements or utilities. Alternatively, you could stay in a hotel. It’s ironic how the CA DMV focuses on the trivial details instead of the more pressing matters.

It’s worth noting that CVC codes 27151a and 27156 have different stipulations. When I spoke to the Ref call center, they confirmed that if you’re cited for CV 27156, you’ll need to undergo a smog check. On the other hand, a citation for CV 27151a typically involves just a decibel test.

If an officer didn’t use a decibel meter to measure your exhaust noise, you can challenge this in court and potentially dismiss your case. Of course, a lot depends on various factors (including the judge’s temperament). [CVC 27156 is about excessive pollution].

The difference between CVC 27156 and CVC 27151 is noteworthy: 27156 relates to modifying smog control equipment, while 27151 is about noise levels. It’s a bit of a gray area, but some folks interpret CVC 27151 (modifying your exhaust to make it louder) differently. They believe it’s legal as long as you remain under 95 dB.

Here’s What to Expect During an Inspection:

  1. Decibel Level Test: A microphone will be positioned 15 feet from your vehicle. The engine will be revved up to 4,000 rpm.
  2. Examination of Exhaust Silencer/Cutout: Inspectors will check for an exhaust silencer or cutout.

One key point is that no smog test will be part of this process. Some folks find it handy to switch to a stock exhaust for the test temporarily. Once they pass, they revert to their Valvetronic or custom exhaust. If all goes well, they’ll get their compliance letter, keeping the car fully bolt-on (FBO). 

There’s also an anonymous tip program where individuals can report others engaging in this behavior. California takes revenue collection seriously. If you’re caught doing it again, an investigation can occur. (Source.)

Cal. Veh. Code § 27151

“Modification of exhaust system to amplify or increase noise prohibited (a) A person shall not modify the exhaust system of a motor vehicle in a manner which will amplify or increase the noise emitted by the motor of the car so that the vehicle is not in compliance with the provisions of Section 27150 or exceeds the noise limits established for the type of vehicle in Article 2.5 (commencing with Section 27200). A person shall not operate a motor vehicle with an exhaust system so modified. (b)For exhaust systems installed on motor vehicles with a manufacturer’s gross vehicle weight rating of less than 6,000 pounds, other than motorcycles, a sound level of 95 dbA or less, when tested by the most current SAE International standard, complies with this section. Motor vehicle exhaust systems or parts thereof include but are not limited to nonoriginal exhaust equipment.”


CHP Rules: Excessive Noise Enforcement Passenger Vehicles, Light Trucks and Motorcycles

The California Highway Patrol (CHP) Commercial Vehicle Section (CVS) has received many inquiries about excessive noise emitted by passenger vehicles, light trucks, and motorcycles. Enforcement personnel and the public have inquired about enforcing the Vehicle Code (VC) sections regarding excessive noise emitted by these vehicles.

Excessive noise is primarily a nuisance rather than a safety concern, and its determination is subjective. For this reason, enforcement personnel are to exercise sound professional judgment when determining a violation. The following guidelines and the attached question and answer sheet (Attachment A) guide enforcement personnel regarding appropriate enforcement procedures.

Enforcement Guidelines


The only drivers who should be cited are those whose vehicles:

  1. Are not equipped with a muffler;
  2. Emit an offensive, harsh, excessive noise or
  3. Have a defective exhaust system (holes, leaks, etc.).

    Clearing Code Noise Citations

When clearing excessive noise citations issued by the CHP or allied agencies, personnel must consider exhaust systems in compliance if they incorporate a reasonably practical muffler, do not emit an offensive, harsh, excessive noise, and appear to be in good repair.

CHP ATTACHMENT A



Q1: Doesn’t the VC require a muffler on every vehicle?
Yes. Section 27150 VC requires that every motor vehicle subject to registration be equipped with an adequate muffler. There are no exceptions — all vehicles must be equipped with a muffler, as defined in Section 425 VC. A turbocharger is not considered a muffler.

Q2: Aren’t all exhaust system modifications prohibited?
No. Section 27151 VC prohibits the modification of the exhaust system to amplify or increase the noise emitted by the vehicle, making the vehicle not in compliance with Section 27150 VC or exceeding the noise limits established in Sections 27201-27206 VC. Section 27151 VC does not prohibit all modifications to an exhaust system. It also does not prohibit all changes that increase the noise level of the exhaust system over that of the original, factory-installed exhaust system (as it did until 1980). It only prohibits modifications that result in a noise level higher than those specified in Sections 27201-27206 VC. Accurately determining compliance with Sections 27201-27206 VC for enforcement purposes is generally impractical. Enforcement personnel must make an informed professional evaluation to determine if excessive noise statutes are being violated.

Q3: Do I have to listen to a vehicle to cite it for violating either Section 27150 or 27151?
Yes. Drivers of vehicles should not be cited for violation of either Section 27150 or 27151 VC unless the officer has personally listened to the car in operation. This can be either under actual driving conditions or with the vehicle stationary and the engine running. Even if the officer has inspected the exhaust system and does not see a muffler present, the officer should listen to the vehicle. The purpose of this is to be sure that the exhaust system does not incorporate internally baffled pipes or other components that meet the definition of a muffler. No specifications state the required configurations or minimum dimensions for mufflers. A vehicle that does not visually appear to be equipped with a muffler but does not emit excessive noise should be deemed to comply with Sections 27150 and 27151 VC.

Q4: Does an aftermarket, replacement, or modified tailpipe or muffler tip violate Section 27151 VC?
No. Section 27151 VC prohibits the modification of exhaust systems to amplify or increase noise. The officer would have to establish that the modification increased the noise emitted by the vehicle by listening to the exhaust. In general, exhaust system piping, tubing, fittings, cosmetic tips, or other passive devices placed behind the muffler have minimal impact on exhaust system sound levels.

Q5: Since Section 27150 requires that the muffler prevent excessive and unusual noise, can the driver of a vehicle be cited for violation of Section 27150 if it emits a sound different than the original factory-installed muffler?
The prohibition against unusual noise applies to motor vehicle noises. Noise that may be unusual for a particular vehicle make or model but not necessarily uncommon for other motor vehicles should not be considered in violation, provided the noise is not excessive.

Q6: Aren’t all modified exhaust systems unlawful under pollution control laws?
No. Current pollution control laws regarding aftermarket exhaust systems are pretty complex, but they permit the installation of various aftermarket and “exempt” systems. Due to the complexity of modern pollution control systems and the laws governing them, the CHP does not provide technical training in this area. Enforcement of pollution control laws is the responsibility of the Bureau of Automotive Repair through the “Smog Check” program.

Q7: What noise levels are specified in Sections 27201-27206 VC? Can these be used to cite loud vehicles?
No. Section 27200 VC prohibits the sale of new motor vehicles that exceed the noise limits specified in these Sections. The specified noise limits (80 dB(A) (decibels) for all new cars, pickup trucks, vans, and motorcycles apply only to new motor vehicles under complete throttle acceleration tests, measured 50 feet from the test vehicle, as specified in Sections 1040-1044, 1046 and 1047, Title 13, California Code of Regulations (13 CCR). These noise levels and the specified test methods apply only to manufacturers and new car dealers for new vehicle certification purposes. They may not be used for enforcement purposes against vehicles being operated on public roadways. The CHP is unaware of any significant violation of Section 27200 VC by vehicle manufacturers or dealers.

Q8: What noise levels are specified in Sections 23130 and 23130.5 VC, and how can they be enforced?
Sections 23130 and 23130.5 VC specify noise standards for vehicles operating on the highway (in-use cars) in actual traffic conditions. The limits of Section 23130 apply under all conditions of grade, load, acceleration, and deceleration. The lower limits of Section 23130.5 apply only to relatively level roadways and under conditions of relatively constant speed. They specifically do not apply to areas of congested traffic that require noticeable acceleration or deceleration, within 200 feet of an official traffic control device, or change in grade. Although these sections were intended for use in actual traffic conditions, the complexities of noise testing require the testing to be conducted in a relatively large open area free of other vehicles and large sound-reflecting objects. This makes in-use vehicle noise testing in most developed areas impractical, where noise complaints are most likely to occur. The CHP does not provide the instrumentation or training necessary for vehicle noise testing. Enforcement using Section 27150 or 27151 VC is usually more appropriate and effective.

Q9: What is the exhaust noise test specified in 13 CCR? Can this be used for enforcement?
Sections 1030-1036, 13 CCR, were intended to be used by Licensed Muffler Certification Stations to determine if an exhaust system met the requirements of the Muffler Certification Program (when those programs were operational). They specify testing procedures for motor vehicle exhaust noise alone (instead of total vehicle noise). This procedure specifies a limit of 95 dB(A) measured 20 inches from the exhaust pipe outlet with the engine operating in neutral, typically at a speed of 3000-5000 rpm. (For comparison, a modern rotary lawn mower with a 5-horsepower Briggs & Stratton engine normally emits approximately 93 dB(A) at the same distance at full speed under no load.) It applies only to passenger vehicles. It does not apply to motorcycles or vehicles over 6000 pounds gross weight.

Q10: Can this test be used in enforcement?
Not readily. Although much more straightforward than the test methods specified in Sections 23130 and 23130.5 VC, this test method still requires some technical expertise and a means to determine both the speed (rpm) of the engine under test (tachometer) and the rpm at which maximum horsepower of the engine is developed (information which may not always be readily available), as well as a sound level meter. It is not intended for roadside noise testing. The CHP does not provide the instrumentation or training for exhaust noise testing. This test is practical, however, for determining if an aftermarket or performance exhaust system complies with VC requirements. It should be noted that the 95 dB(A) level, because it is intended as a simple “go-no-go” type of test, may permit exhaust noise somewhat higher than those permitted under Sections 27201-27206 VC. An exhaust system that complies with the requirements of Section 1036(d)(1), 13 CCR, is deemed to comply with Sections 27150 and 27151 VC.

Q11: What happened to the Muffler Certification and the Licensed Certification Station Programs?
Funding for both programs was terminated in 1979. There are currently no Official Muffler Certification Stations, no listing of certified mufflers, and no formal mechanism to conduct objective vehicle or exhaust noise testing.

Q12: Can local authorities enact or enforce more strict ordinances regarding vehicle noise?
No. Section 21 VC makes the VC applicable and uniform throughout the state and prohibits local authorities from enacting or enforcing any ordinance on the matters covered by the VC unless expressly authorized. In-use vehicle noise [and Noise abatement equipment modifications] is addressed in Sections 23130 and 23130.5 VC. No provision in the VC permits local authorities to adopt additional noise limitations. Consequently, citations issued under such ordinances are invalid.

Q13: Some aftermarket exhaust systems include documentation that the system has been tested and found to meet the requirements of Section 1036(d)(1), 13 CCR. Are those legal?
The CHP does not have the resources to independently verify manufacturer claims. Still, it is known that some aftermarket exhaust systems meet the noise levels specified in Section 1036(d)(1), 13 CCR. An officer may consider such documentation when evaluating an exhaust system for excessive noise, both during the issuance of a citation and when clearing a citation under Section 40610(b) VC.

Q14: What enforcement action should be taken against vehicles emitting excessive noise?
Providing none of the disqualifying conditions listed in Section 40610(b) are present, the use of the CHP 281, “Notice to Correct,” or checking the Dismissable Violation “Yes” box on the CHP 215, “Notice to Appear (Arrest Citation),” would be appropriate for these violations.”

How Loud is Too Loud for an Exhaust System? – In The Garage with CarParts.com

Performance cars are known for their magnificent exhaust notes. Muscle cars boast a thunderous V8 roar, while supercars deliver a jet-engine-like symphony. Modifying the car’s exhaust system often becomes the go-to solution for enthusiasts wanting that unique exhaust sound. Still, on a budget, a mod critical player in engine noise is the muffler resonator. Since 2019, monitoring exhaust sound levels has been crucial, especially in California. New laws affecting exhaust modifications and muffler systems might have implications beyond the state’s borders. 

You can still buy aftermarket exhaust systems in California if they adhere to the 95-decibel limit. AlterTheuct must meet noise level regulations if tested per SAE J1402 standards.
