I live in the smog nazi state of California. any one with a 3rd generation rex this is a question for you. do u have problems passing smog?? i want to redo all the turbos and piping if i get a rex and i was wondering if it wouls still pass smog?

I DON'T have a rex, but I know if I did have one I'd use a smog additive just to make sure I passed.

That stuff works great for any car.
