Hey guys, this is my first post on here and I have a few questions that maybe some of you guys may answer.

I just received my invidia midpipe for my IS 250, but I’m worried when it comes around smog time, as I do live in California.

will I have to swap it out for the stock midpipe just for me to pass smog?

last question, is there any complications when it comes to installing the midpipes? I know some people have had trouble taking out the o2 sensors so I just bought an o2 sensor socket.
