The Predator headers (actually they look like they're made by JBA - you may be able to get a better price directly from JBA) being shorties can be CARB'ed pretty easily. The Dynatechs, being long tubes with new mid-pipes and cats, would be next to impossible to CARB certify. You're replacing the cats on a new vehicle and possibly moving the position of the O2 sensors...both "no-no's" on a new smog equipped vehicle. So they've got no choice but to label them 'Race' or 'Off-Road Use Only' but all of the Lightning guys have replaced their exhausts with Dynatech/Kooks/Bassani headers and high-flow mids and cats and no one's had an issue 'smogging' their vehicle.
