Exhaust Pipe sound rules.

[Country_boy396]

I have a question for all of you.

What are the rules to define how loud pipes are handled? I own a 78 Chevy 4X4 that I must drive across three counties and one state line to enter in an off-road competition. My mom says that the truck is far too loud, but she is sensitive to loud noises.

As far as pipes go, the truck has the required piping and sound muffling parts all the way until the end of the glasspack muffler, then the pipe was cut off flush with the end of the muffler.

I wouldn't say the truck is too loud, but it would be plenty loud enough to wake up a person sleeping inside a house. It is almost too loud to talk over if you are standing beside the truck.

I would love to avoid having to trailer this truck, because it is so heavy and tall. It is tagged in my name, and is insured also.

What are my chances of getting pulled over and ticketed because of loud pipes? I don't need a ticket right now. Could I make the trip if I keep my foot out of the gas inside city limits?

You would have to check with your local PD. Here, you cannot have anything that makes the exhaust louder than the stock exhaust system.

Kansas Statute 8-1739 Mufflers and noise suppressing systems
(a)Every vehicle shall be equipped, maintained and operated so as to prevent excessive or unusual noise. Every motor vehicle at all times shall be equipped with a muffler or other effective noise suppressing system in good working order and in constant operation, and no person shall use a muffler cut-out, bypass or similar device.

So at least here if you have a good set of pipes and glasspacks that are not blown out you would be okay. Not to say they are not on the noisy side, but legal as far as I can tell.

If you have the length under the truck, try stacking two glasspacks. Tones it down and you won't lose much if any HP. That or try turbo IIs.

If I can hear yours over mine, it's too loud

Anything louder than stock.

a) No person shall drive a motor vehicle on any road, street or highway unless such motor vehicle is equipped with a muffler in good working order and in constant operation to prevent excessive or unusual noise and annoying smoke.

b) It is unlawful to use a "muffler cutout" on any motor vehicle upon any road, street, or highway.

That would be illegal in VA. as it permits a louder exhaust note than a stock system. If I can hear you before I can see you then it's too loud and your apt to get a summons.

Same here.
