Need some help with noise laws

[Axle]

Been down that road more than once.
First off, find out what kansas has on the books about muffler and exhaust requirements.
If its simple like ours;
Proper muffler(s), no holes, no remote control cutouts, no holes, and exits beyond the passenger cabin you are good to go. No db limits on the books. Yet.

If you comply, its straight forward: 'Hey man, it doesn't bother the cops, and I've been followed a lot, and it is completely legal front to back'. Usually shuts up the smart ones if they are trying to get you technically.

Of course, theres the, how much misery do you want to give your neighbour? Warming up my truck is what made me (personally) get rid of the magnaflows on my truck after a week. Just too darn loud to be idled up in the driveway, just outside the neighbours windows, just outside my own house bedroom windows where people are still asleep when I'm heading off to work. . My final solution was to go back to standard turbo mufflers. Toned it down a lot for the cold morning warmups and everybody is happy, myself included. This is coming from a guy who loved tooling around with open headers in my car, and setting off car alarms with my trucks exhuast when I had turn downs pointed just right.

So, pick your battles carefully, and consider the circumstances when you are firing up the truck first thing. If its at o-dark-thirty, keeping the peace with neighbours is worth it in the long run with a goodwill gesture of quieter mufflers--it ain't gonna make that big a difference in performance. And theres the rest of the neighbours around you to, who may be tolerating it, but don't want to bring it up with you for whatever reasons.

(I must be getting old...mufflers!? quiet!? appeasing neighbours!!??!!??)

quick googling;

8-1739 Mufflers and noise suppressing systems.

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.

(b) The engine and power mechanism of every motor vehicle shall be so equipped and adjusted as to prevent the escape of excessive fumes or smoke.

Local ordinance might get you even with legal components if it comes down to being a judgement call by code enforcement or the cops;

Section 7.41.010 Loud and unnecessary noise prohibited.
(5) Motor Vehicles. The use of any motor vehicle, motorcycle, bus or other vehicle so out of repair or in such a manner as to create loud or unnecessary grating, grinding, rattling, or other noise which shall annoy, distress, or disturb the quiet, comfort, or repose of any person of reasonable sensibilities within the vicinity.
