For you guys that have test pipes...

What do you do when you have to get the car inspected/emissions tested? Can you just clamp the OEM cats back on? Will the ability to do this vary between the brands of test pipes? And I'm assuming for you guys that have a tune, you'd need to reflash back to stock? If so, how long will I need to drive before everything readapts? I'm in TX so it would be an annual thing for me which may or may not be worth it...
