328i Performance Exhaust in California

I'm thinking about getting the BMW performance exhaust for my 07 e92 328i with the n51. For those who live in California, I was wondering if any of you guys out there with the performance exhaust have had an issues with smog testing?

Since its made by BMW, I figured they would have taken emissions into consideration? I've seen that the performance exhaust requires removal of the oem secondary cat or is it a resonator on the n51? Also since the n51 is a lower emissions engine, would it be an issue? Or is there just a emissions standard limit that vehicles have in California?

Thanks in advance guys!
