Ticket for straight Pipe...
#31
The officer did not use the speed violation as a reason to check out the muffler. That assumes the officer was prohibted from stopping the guy for the muffler violation alone. Bottomline: It is a question of "Probable Cause". Anytime an officer feels he has reason to believe you are in violation of the law he is allowed, within specific constraints, to investigate further.
The initial reason for the stop be it speed or muffler then gave the officer 'Probable Cause' to pursue any other readily apparent violations. This is why it is usually to your advantage to be cool and polite. The officer may be less inclined to flex his muscles.

Honestly, I read that, and I can interpret it either way. Where I think you'll hit a dead end with a judge is the "intent" of the statement (about mufflers and turbos). Even though it is NOT clear, I believe the intent to be a multi-chambered device receiving gases from an engine or turbo. And a judge would too.
The thing about those boom box radios (which personally I don't have a problem with unless they're keeping me and others awake, or disturbing a nice quiet place) is that when they see the poe-lease, they can turn them down. You can't really turn down a straight piped Cummins, but just so far. If you're pullin', forget about it.

CA has a noise requirement for mufflers.
But there is no law that states you can't replace your muffler.
And I've never heard of a book that has a list of approved list of mufflers, though that's not to say it doesn't exist.
With the exception of my CTD, I've had full custom exhaust systems on all of m vehicles and never ran into trouble.
Thanks to SEMA action, the onus is on the state to prove your muffler is too loud. You definitely CAN get a ticket, but the ticket states that you take it to a station to test for excessive noise before any punishment is levied. In other works, just because the cop says it's too loud, doesn't mean that you automatically get a fine.
CA Vehicle code:
27150. (a) Every motor vehicle subject to registration shall at all times be equipped with an adequate muffler in constant operation and properly maintained to prevent any excessive or unusual noise, and no muffler or exhaust system shall be equipped with a cutout, bypass, or similar device.
Vehicles are tested for noise compliance ONLY if the officer deems it as being too loud. The owner must then go to a test station to see if the muffler is indeed too loud or not:
27150.2. (a) Stations providing referee functions pursuant to Section 44036 of the Health and Safety Code shall provide for the testing of vehicular exhaust systems and the issuance of certificates of compliance only for those vehicles that have received a citation for a violation of Section 27150 or 27151.
Limits for Vehicles Exceeding 5,999 Pounds Gross Vehicle Weight
27204. For the purposes of Section 27200, the following noise limits shall apply to any motor vehicle within the specified manufacturer's gross vehicle weight rating and date of manufacture:
[Noise limits for vehicles with a gross vehicle weight in excess of 5,999 pounds.] * GVWR-Pounds Date of Manufacture Noise Limit -dbA
Over 6,000 after 1967 and before 1973 88
Over 6,000 after 1972 and before 1975 86
Over 6,000 after 1974 and before 1978 83
Over 8,500 after 1977 and before 1982 83
Over 6,000 but not over 8,500 after 1977 80
Over 8,500 but not over 10,000 after 1981 80
Over 10,000 after 1981 and before 1988 83
Over 10,000 after 1987 80

I cannot speak to California law, because there are more fruit and nuts lawmakers there than anyone can keep track of, but I categorically can state there is NO Federal law regarding "approved" Mufflers. I think you may be thinking of Catalytic Converters of which there are very strict Federal replacement guidelines.
Post Catalytic exhaust systems are not covered by Federal laws.
Not arguing with you about the Turbo thing, because I read it as being to receive gasses from an internal combustion engine or a turbine.....

It is currently against Federal Law for a heavy truck operator to tamper with the exhaust system. It has been illegal for decades to tamper with throttle delays or fuel modulators. These were fuel system management devices that related to exhaust ie: smoke & pollutants.
Commercial enforcement (Commercial Vehicle Safety Alliance) standardized nationwide against heavy trucks in the mid 90's. An officer in Ohio now enforces exactly the same federal laws as an officer in Oregon vs heavy trucks. When the local highway patrol stops a heavy truck he is enforcing both state and federal laws.
The Commercial Drivers License came out of that standardization. A CDL is now a national license. Officers in any state have access to your record.
With the CDL for example it is impossible to obtain a second license from another state. Further, if you recieve a citation in Calif. it will show up on your home state record and they will collect the fine.
Again, sorry I drifted and did not clearly differentiate.

K, Thanks Dr, I learned something also, I never have had to deal with the Commercial side, kinda sounds like they would like to get their feet in the door messing with Truckers, then snare us "normal" users with the same BS.

Federal noise law:
"The removal or rendering inoperative by any person, other than for purposes of maintenance, repair, or replacement, of any device or element of design incorporated into any new vehicle for the purpose of noise control prior to its sale or delivery to the ultimate purchaser or while it is in use". The EPA regulations also prohibit the use of a vehicle that has had the noise control system rendered inoperative. This is stated clearly on a label required on all vehicles sold in the U.S. and is fully explained in the operator's manual for every new truck. The improperly muffled vehicles, especially those with straight stacks, are not operating in compliance with current federal regulations.

Does it matter who agrees or disagrees? Fact is that it is illegal to change a factory system on any vehicle. That being said, if you have the muffler on the truck and have retained the cat, stacks are ok as they are a truck safety feature to keep exhaust from the passenger compartment.
Also to get technical and practical, it is better to have a defective unit than having removed it. That twist can be used in different ways.

Living here a straight pipe is no problem but if you are in an area that enforces a muffler, what we used to do, even on big trucks, get a muffler that the inlet and outlet line up, get out the cutting torch and install a straight pipe through it, weld it back up. When they look there is one, not really but they don't know that. Same as gutting a cat.
For the cop it takes the fun out of it, too loud verses no muffler.

Yup. Im gonna do it with my old ford gasser muffler so I dont ruin my good muffler, in case I ever stick it back on.

I don't think that's true at all.
You can replace it with another, but you can't remove it completely. That's how it's written both federally and on the state level (most states anyways).

Good example is when California wanted more restrictive emissions laws than the feds and the Supreme Court said no.

Generally from what i have found in the past if you drive like a dumb -x- then you will get a ticket one way or another!
i do 9 MPH over the speed limit all the time if i hit 10 then they will flash there lights at me. I have 6 inch stack and if that dont say no muffler i dont know what does. i have been pulled over for no plate when i first got it and i only had my down pipe and that was it and i left my truck run the whole time but i was respectful to the officer and showed him the papers he needed to see and he never said a thing about my lack of any sound dampening device.
My friend has a mung car with the fart pipe and he went around his neiborhood laying down rubber and doing at least 50 mph in a 25. sure enough with in 10-15 minutes the police came a knockin! It was this ladie cop that reamed him a new one but counldt do anything really because she had no proof. When you drive like that what do you think there gona do next time when they have proof.
