Im about to purchase a del sol which is registered in Illinois and i live in texas. It already has a injen cold air intake, hp 4-2-1 headers, obx n1 full catback installed on the car. So I was wondering if it will pass smog with those installed or do i have to return everything back to stock for it to pass smog? And is it difficult to register an out of state car once I buy it from him?
