07 engine swap (different emissions)

Yes it's that easy normally California emissions is exhaust related so just use your existing manifold when you put the new engine in

@Guru94P96R, is the EGR system or other components different? I only ask bc the lower emissions are reduced somehow & I'm not educated on the subject (& can't find anything on the subject)

Also as always when your doing a swap when you have the engine out set it next to the new engine and you want to make sure all sensors and everything match the engine that came out of your car. So swap over whatever you have to and keep it simple as possible
