hey guy just passed emissions with non resonated test pipes by using the spark plugs non-Fouler trick. Got them from advance auto parts it really works even got rid of the check engine light I was so happy that I didnt have to fork over the $250 to have somebody passed my emission that i finally became a member on this forum to let anybody having trouble passing emissions with test pipes that it really does work

 

We have known about the non fowlers for years, that just keeps you from getting the error codes on your dash. What it doesn't do is allow you to pass the sniffer test and or the visual test in CA. or most other states!

I know everybody knows about the trick I'm just saying it works for anybody that needs that info but I don't know about Cali I live in Atlanta and they have pretty strict emission laws i passed the sniffer test thats what surprised me and as far as a visual test my cars too low.
