here is the skinny about Smog in cali.

By law you are not allowed to relocate the OEM or replease the OEM cats. Shorties are legal as long as long as u use oem spec cats. Long tubes relocate the cat so it blows the smog. Also another issue is if you replace your headers with a set of long tubes it forces you to reprogram your computer to disable your O2 sensors which will also fail smog. Bottom line is that LT's will never pass california state emitions.
