Hi, I have a WS Y-pipe and a Car Sound Cat and I was wondering if it will pass smog fine? Has anyone have any problems with passing smog with the Y-pipe upgrade?

Also if I were to get a Apexi WS or a B-Pipe w/ muffler will it still allow me to pass smog?

Oh yeah, I live in CA just to let ya know. Sorry for being so newb >_<

Thanks in adavance

and make sure your car is well-warmed up before the smog. (aka warming up the cat). drive it around for 30 minutes like a **** around the street without getting pull over by cops then go smog, u should pass no problem.

If you need to wait to get on the rollers for the test, make sure to leave the car running, helps keep it nice and warm. Having my car sitting off for about a half an hour cooled it enough to have me fail the test, We ran the test again right away and I passed fine.
