Do cops pull you over for loud exhaust?

What happens if you don’t fix catalytic converter?
Because a failing catalytic converter can no longer properly convert the toxic fumes that flow through it into less harmful materials, one of the side effects that you are going to experience is the smell produced by the gases flowing through it. In particular the exhaust is going to have a sulphur type smell.
How much HP does removing a catalytic converter add?
Removing the cat will have almost zero impact on engine HP. The exhaust will be slightly less restrictive, but that will cause unnoticeable gains. A more effective way to boost HP is to retune the engine, by advancing the timing.
Does removing the catalytic converter make it louder?
Just like how the purpose of a muffler is to muffle the loud noise caused by the exhaust exiting your vehicle, the catalytic converter does the same thing. If you remove your converter, you’re giving your car a louder and more distinctive sound.
Do bad catalytic converters make noise?
Rattling noise Rattling noises are another symptom of a bad or failing catalytic converter. If a catalytic converter becomes old or damaged internally from excessively rich fuel mixtures, the catalyst coated honeycomb meshes on the inside of the converter can collapse or break apart, causing a rattle.
Is it safe to drive with a loud exhaust?

What does a blown catalytic converter sound like?
Rattling Noises. Your catalytic converter consists of small, honeycomb-shaped components that can cause a rattling sound when broken. If your catalytic converter is broken, this rattling should be loudest when the car starts, and should get worse over time.
Why does my car exhaust sound louder?
Leak in Exhaust Manifold: The exhaust manifold collects exhaust gases from the engine. If there is a leak in the exhaust manifold it can cause the engine to run louder, sputter and run unevenly. … It is also possible for leaking exhaust fumes to find their way into the cabin of the car.
Do cops care about loud exhaust?
The vast majority of officers don’t really care, unless it’s exceptionally loud. Those who stop and cite motorists for that violation just really have nothing better to do. A loud exhaust is not legislated in any “unsafe” motor vehicle statute. Most are legislated in “noise” statutes.
