Failed Smog!!!

do you smog it with RXP in the tank? What was your NOx number?

I didn't use it this year...and barely passed. I'll take a look at my previous results and see what it says. When I used it on '05, the results were better than new.
 
Just saw this thread.

Driving the car like a madman to get the cats nice and hot has done more for me in the past than any over the counter additive I have tried.

Just find a place where they will let you keep the car revved up until the very moment they run the test. The last time I had my car smogged the guy let me rev it on the dyno and everything until the test begun.

Obviously change your oil, plugs, filters, etc.
 
How did you fail smog? I almost passed with no cats, headers and exhaust!
 
I passed my smog today. Both my cats where brocken. So i installed a third cat and baam, it passed. Now i can continue my turbo project at ease.
