It is no secret that a car will run better if the exhaust system is free of all catalytic converters and mufflers that can choke the engine. However, in the quest to meet safety regulations, manufacturers install multiple exhaust monitoring sensors, mufflers, and components to pass emissions tests. However, in recent years, most manufacturers are able to produce fast and powerful yet still environmentally-acceptable sports cars.
But some people remove their mufflers to “free” the engine. But by doing that, they mess with the engine’s electronics and ruin any warranties they have. Also, they’ll have big problems with the law since they clearly forbid cars with emissions equipment missing.
One of the least expensive yet fastest things you could do to mod your car is to change the headlights. With so many quality brand name replacement units, you can give your ride a facelift, but also get the best level of light and visibility. However, some people choose low-quality replacement headlights to save money.
And they not only ruin the looks, but they also reduce the visibility factor of their car. It is against the law to add headlights that are either too dim or too bright. Both the driver and oncoming motorists must be able to see.
Radar detectors are a burning question in the car community. Some states consider radar detectors illegal while others allow you to have them. But, if the police prove that you have been using one, you’re going to get a ticket. Also, they are becoming obsolete due to a new generation of police speed radars that use cameras and calculators to determine your speed. That means there are no radar waves to detect or jam. In most cases, police radars send radar waves that bounce off the speeding vehicle and return to the radar, which calculates the returning speed; thus, showing the speed of the moving car. Radar detectors work as a jammer or as an alerting device. The jammers cause police radar to get bad return signals and disable them from reading the speed properly.
The alerting device tells you there is a radar up the road, so you can slow down in time. In the past, radar detectors proved to be effective, saving many drivers a lot of money. The problem is they also gave motorists the confidence to drive faster, which is unsafe. Today’s radars work more like a camera that calculates the moving speed with great precision. And since there are no radar waves, it is impossible to jam or detect them. So if you already have a radar detector, conceal it and never put it in a visible place like the bottom of your windshield. And finally, if you are planning to buy one, save your money and just drive the local speed limit.
Yes, it’s true that a powerful car needs to have a distinctive and strong exhaust sound. There is no better sound than a raspy V8 on idle. And while a big part of the automotive culture is about the loud exhaust pipes, it looks like the insanely sounding muscle cars are going to be extinct. That’s because most states forbid loud exhausts and ask manufacturers of such systems to tune them to legal decibel limits. It is possible to have a quality-sounding exhaust powerful enough to let you know you are in a fast car. But they can be quiet enough, so they don’t wake up the neighborhood or start car alarms.
One of the major concerns in urban areas is noise pollution, and much of it comes from cars and other vehicles. So, to keep the noise levels down, police are cracking down on homemade straight pipe exhausts that are louder than approximately 90 decibels.
Pickup trucks are the automotive symbol of America and they had been around forever. This means that pickups are the basis for all kinds of modifications. A popular mod is those lift kits that add extra ground clearance for better off-road driving. Also, those lifted trucks look cool and tough, and millions of truck enthusiasts agree. But some drivers take it too far. Commonly known as “Bro Trucks,” those extremely lifted pickups have been popular in recent years, but also illegal in some states. The problem is not with the concept of more ground clearance, though.
In fact, there are numerous two to three-inch lift kits that will perfectly suit your truck and make it more capable. The problem is when you lift your vehicle two to three feet more than stock. This way you get a truck that is hard to get in and out of that handles poorly and is prone to rollovers. Also, if you are having an extremely high vehicle, it’s hard to see and maneuver in tight spaces, such as parking lots or crowded streets. All this makes extremely lifted Bro Trucks illegal in some states. In fact, most states have imposed the maximum limit for bumper, hood or light height for each specific vehicle class.
Despite the affiliation with criminal gangs, Lowriders are one of the coolest, most impressive types of custom vehicles. Low and lean with wild color schemes, beautiful graphics, shiny chrome and hydraulics systems, how can they be illegal? Apparently, apart from being police magnets, they are also against the law in some states.
The problem with Lowriders is their ride height. They are so low, they scrape the pavement, which results in the police having to be on the lookout. Some cities allow Lowriders and their signature hopping, but only when the cars are stationary or moving below 15 mph.
For decades, laws have prohibited the use of adding flashing red and blue lights to vehicles to keep people from acting like the police. People have used faux police lights to zoom through busy traffic with ease since the other drivers thought they were letting the police go by.
But when neon lights became popular in the early 2000s, things got even more complicated. When done right, neon can look cool, but still, having an underbody glow can distract other motorists. And that can cause accidents, and eventually a ticket.
In some parts of America where the continental climate is harsh and the winters are long, studded tires are a good way to fight icy roads. This is perfectly fine while the weather is cold. But if you use studded tires during spring or summer, you are up for a big fine.
The reason is simple, they make studded tires to dig into the ice. However, when there is no ice on the road, studs can damage the road surface and destroy the tarmac.
If you are a serious racer you know that the tires are a crucial part of a car’s dynamics. In fact, performance tires are a must for any powerful car. However, some racers use slick tires with racing rubber they design to perform best on the track.
To show off, some drivers mount slick, racing tires on their streetcars and drive around. Unfortunately, doing that is highly illegal since slick tires are useless in the rain and in normal traffic. So, don’t use them, or you will get a big fine.
Some people think they are clever to add blue and red lights on their cars to imitate the police car and pass through the traffic with ease. But when they get caught, they not only get an enormous fine but also criminal charges and possible jail time. So, never install a set of blue and red lights behind the grille of your Crown Victoria, since you could end up in major trouble.
These are the top 20 car mods that are illegal almost everywhere in the USA. Have you ever had one of these mods on your car? Hopefully, you didn’t end up behind bars for using it.
