magnaflow header?

So I have been looking into headers for my 2011 2.5 mazda 3, but very hesitant on upgrading them because I live in California and of course having headers it won't pass smog. However, I found a magnaflow header that has an integrated CAT so it might pass smog. But i have not read any reviews on it and could not find anything about it. So if anyone has any experience on this that would be appreciated.

That could be possible that its too new to have reviews. If anything I may take a chance on it. Or contact magnaflow and see if they have any dynos or anyone who has had experience with the headers.
I went ahead and emailed them and this is what they said, " Part number 51440 is a FEDERAL DIRECT-FIT catalytic converter. It is not a performance header" I guess that answers our questions haha
