Hawks Longtube Header Look awesome and i really want them but the problem is that i live in cali. Are those headers smog legal or what? I know i can get the AIR with it but it seems i need more than that. Can someone help me out PLZ

no CARB-EO AFAIK, hence illegal.

any type of long tube header is not smog legal in CA.

Just Great!!!!! I heard that short tube headers wont do anything maybe just hurt my performance is this ture? So im better off just leaving the stock ones huh?

Will long tube headers work with the LT1 engine swap??

Shorites on a basicly stock LS1 wont net to much gains but they will help when you start modding (heads and cam), they just wont be on the same leval as the long tubes.
