Thread: VS Cam Build.

from what i see here in this link, headers are allowed as long as you have the emissions hooked up they should be fine. and did see slp headers for GM trucks in the list as approved. they seem to allow just about anything you want as long as it passes a smog test and the obd2 scan.

sencond link did not work, got to the top link here, then go to the second drop down search box, look for "Exhaust System / Exhaust Modification" then search.

Havent gotten a chance to read the link but here in Cali for any modification you have to have a Carb approved sticker intake, headers or any modification it can pass emission but they want to see the sticker did smog two months ago didn't pass because of my intake had to take it off and out stocker back on.
