What are some of the things you can do to a car to make it street illegal? I know removing the cat makes you fail an emmissions test, but what are some other things?

why do you want to know?

Neon, you cant pass the inspection if you have it

taking your headlights out....that is unless you're in detroit or kansas.

driving without a windshield
driving with no bumpers....

Check your LOCAL LAWS. It's different everywhere

and, moved to a more appropriate forum.

NAAWWWWWWZZZZZZZ!!!!!!!!!

I think he is talking more along the lines of modifications that are illegal, like aftermarket things.

You can't lower your car too much. There is a minumum gorund clearence.

I didn't know that, do you know why thats illegal?
