Lawmakers argue that the lights can be distracting to other drivers and may impersonate emergency vehicles. However, underglow lighting is undeniably cool and adds a unique, eye-catching aesthetic to any car, making it popular among car enthusiasts who enjoy standing out at night.

Loud exhaust systems, which amplify the noise of a car’s engine, are illegal in many places due to noise pollution regulations. These modifications often involve removing or altering the muffler and catalytic converter. Despite being illegal, loud exhausts are loved by many car enthusiasts for the aggressive sound they produce, which enhances the driving experience and gives the car a more powerful presence on the road.
Tinted Windows

Heavily tinted windows are illegal in many states because they can obstruct a driver’s view and make it difficult for law enforcement to see inside the vehicle. Despite this, dark tints are popular because they provide privacy, reduce glare, and give cars a sleek, stylish appearance. Many drivers also appreciate the added protection from UV rays that tinted windows offer.
Nitrous Oxide Systems

Nitrous oxide systems (NOS) are illegal for street use in many places because they significantly boost a car’s power, which can make the vehicle more difficult to control and increase the risk of accidents. However, NOS is a favorite among performance enthusiasts because it provides an incredible surge of speed and power, making cars much faster and more exciting to drive.
Radar Detectors and Jammers

Radar detectors and jammers are illegal in many areas because they interfere with police radar and lidar speed detection equipment. Despite the legal issues, these devices are popular among drivers who want to avoid speeding tickets. The ability to detect and jam police radar gives drivers a sense of control and freedom on the road, allowing them to drive at higher speeds without fear of getting caught.
Modified Headlights and Taillights

Aftermarket headlights and taillights, including HID and LED conversions, are illegal in some regions because they can produce blinding light that distracts or impairs other drivers. However, these modifications are popular because they improve nighttime visibility and give cars a modern, high-tech look. Custom lights can also be a way for car owners to express their personal style.
Lowriders

Lowrider modifications, which involve lowering the car’s suspension system, are illegal in some places due to safety concerns. A car that sits too low can have difficulty navigating speed bumps and uneven roads, and the modification can also impact the vehicle’s handling. Nevertheless, lowriders are beloved for their unique appearance and the smooth, distinctive ride they offer, making them a staple in car culture.
Engine Swaps

Engine swaps, especially those that involve replacing a car’s original engine with a more powerful one, can be illegal if they don’t comply with emissions regulations. Despite the legal risks, engine swaps are a favorite among car enthusiasts because they can dramatically increase a vehicle’s performance and create a custom driving experience tailored to the owner’s preferences.
Stretched Tires

Stretched tires, where the tire is narrower than the wheel it is mounted on, are illegal in some areas because they can compromise the vehicle’s handling and safety. However, this modification is popular for its aesthetic appeal, giving cars a distinctive, aggressive stance that is highly prized at car shows and among automotive enthusiasts.
Extreme Camber

Extreme camber, where the wheels are tilted significantly inward or outward, is illegal in many places because it can affect a car’s handling and tire wear. Despite this, extreme camber is popular in certain car communities for its unique look and the skill required to achieve and maintain it. It gives cars a striking, unconventional appearance that stands out.
Rolling Coal

“Rolling coal,” which involves modifying a diesel engine to produce large amounts of black smoke, is illegal due to environmental and public health concerns. Despite being frowned upon for its environmental impact, some diesel truck owners find the modification appealing for the dramatic visual effect and the statement it makes about their vehicle’s power.
Hood Scoops

Aftermarket hood scoops, especially non-functional ones, can be illegal if they obstruct the driver’s view or fail to meet safety standards. However, hood scoops are popular for their aggressive, sporty look. Functional hood scoops can also improve engine performance by increasing airflow, making them a favorite among performance enthusiasts.
Off-Road Lights

Excessively bright off-road lights are illegal for on-road use in many places because they can blind other drivers. Despite this, off-road lights are popular for their rugged appearance and the improved visibility they provide during nighttime off-roading. They add a utilitarian, adventurous look to trucks and SUVs that appeals to off-road enthusiasts.
Racing Seats and Harnesses

Widebody Kits

Widebody kits, which involve adding extensions to a car’s fenders to accommodate wider wheels and tires, can be illegal if they alter the vehicle’s dimensions beyond legal limits. Despite this, widebody kits are loved for their aggressive look and the improved handling that wider tires can provide. They give cars a bold, custom appearance that stands out.
Lift Kits

Lift kits, which raise a vehicle’s suspension, can be illegal if they exceed certain height limits due to safety concerns. However, lift kits are popular among truck and SUV owners for the off-road capability and commanding presence they provide. A lifted vehicle can navigate rough terrain more easily and offers a higher vantage point, which many drivers appreciate.
Aftermarket Steering Wheels

Loud Car Audio Systems
