Most states have yearly inspection and emission checks, some (like the
state I live in) have neither.
Some states, like California, make it mandatory that you get your cat
from the factory and any rookie inspector will fail your car by not
following that rule. Your circumstances depend on what state you live
I'm not saying that you should break any state or national laws, but
if you are allowed a generic cat, go for it.
Of course, the big question is......what made the cat fail in the
first place? If you haven't figured that out, you'll be doing this
again in a few months, especially with an aftermarket cat.
Yes it's possible.. just not a great idea.
OBD2 cats are more efficient and expensive.
Tossing a generic cat can cause p0422 (i think?) a cat efficiency code
and turn the light on.
Do you have to get your car smogged where you live?
