Anyone have the CARB approved Magnaflow headers and midpipe?

I live in CA. There are some headers and midpipes I wanna buy but the seller says they will not ship to CA residents since they’re not CARB approved

So my choices are the Magnaflow CARB approved headers and midpipe.

If you have them installed, how do you like it? Any power increase. Can’t really find any info/reviews on forums
