legal/illegal questions..., wondering what's "legal" Options

[MaskedMan]

Alright, well i have a few questions on what is or isn't illegal, and was kinda hoping someone would know or have any information on the subject. I live in LA, and i was just kind of wondering what mods are actually illegal.

Engine mods. I heard many different things like, ANY engine mod is illegal including a short ram intake. Can anyone add to this?

Are cars required to have mufflers? Cause mine was kind of hacked off and stolen off my car while i was away. Car now stays in my garage until i go back.

Nitrous Oxide. Is it legal to have it hooked up in your car?

RHD conversion, Legal or Illegal?

Dark window tint. what is the legal limit? i've seen some pretty dark tint on all of the windows.

Changing to an aftermarket steering wheel.

Front license plate. Are they required?

And i've always kind of wondered but is underglow completely illegal, or is it just red and blue underglow that is illegal?

Ok any help would be great, im just kind of curious about this stuff, cuase i hear it debated all the time, but i never get a clear answer.

Cali is always different but I'll give it a try...


ANY engine mod is illegal including a short ram intake. that doesnt make much sense, I don't believe it

Are cars required to have mufflers? I believe so, if not you at least need the catalytic converter for emissions purposes. if thats requred here they are most likely required in Cali

Nitrous Oxide. Is it legal to have it hooked up in your car? I don't believe it's street legal

RHD conversion, Legal or Illegal? legal. cops could care less. the issue with that is that RHD cars are imported and may not be DOT and emissions legal. and some may argue that its harder to drive on the right side of the road with a RHD. but those aren't issues with legality

Dark window tint. what is the legal limit? differs by state.

Changing to an aftermarket steering wheel. to the best of my knowledge if the car came with an airbag in the steering wheel and the aftermarket one does not it is illegal

Front license plate. Are they required? if you were issued 2 plates your required to have 2 plates. there are ways around that though. i don't have mine on. there are multiple discussions about this

And i've always kind of wondered but is underglow completely illegal, or is it just red and blue underglow that is illegal? they are not street legal. you can get fined for it
