ok, you know how when people have car insurance, they can report whatever "aftermarket" they put on the car and report the pricing so that when the car is parted out of what not, they can get that amount back right?

so with rims, exhausts, intakes, etc it should be pretty easy to report the amount paid and have those parts insured right?

ok, well, here is my question.. how do insurance companies deal with.. say... turbo kits. because to my understanding, some turbo kits aren't exactly street legal.

so more specifically to the KA-t guys(but not limited to), do you guys even report that as something you added on your car?
will the insurance company refuse to cover those parts if they are not street legal?
or can you just say you "bought aftermarket performance modifcations for the engine"?

also, do you need to have some form of receipt for the parts you bought? how do they make it all official so that you can/cant trick them that you paid 10,000$ for something u got for 100$?
