Hey everyone! It's been a while since I've been on the forums. I've recently installed a bunch of mods on my 2003 AT WRX. Why you ask an AT? Just for kicks. Thing is it won't pass smog, not even the on board monitors. Is there anyway that I can pass smog with out having to put the car back to stock and re-install. Thank you everyone!

List of mods:
AEM Short Ram
Perrin Up-pipe
Perrin Catted Dp
Perrin Equal Length Headers
Tanabe Touring Exhaust
FP Evo 3 16g
750cc DW Injectors
255L Fuel Pump
Cobb AP

 

E85?

 

You should be able to have that tuned and pass the sniffer. You will NOT pass a visual anywhere. So if you smog at a place that doesn't look and only cares about the sniffer numbers then you're good.

Just get a smog tune. Mix in some E85 and heat up that cat. Then go try it. Worst that could happen is you fail and you have to hustle to return it to stock and do it all over again.

 

Not just the cat, the new smog checks the ECU, so you need to get enough data in there with the e85 for it to show good. No way around that now AFAIK. My truck's motor is stock and the battery died. Had to jump it to take it to smog and even though it is stock, they wouldn't pass it because there wasn't enough data logged by the ECU, but it passed sniffer. Dude said to go drive it for 30 min and come back; ran a few errands and it passed.

 

With all those mods, I hope you've tuned the car...HAHA.

 

Stock cat should get you passed the sniffer. Throw in some e-85 for good measure

 

stock downpipe and stock intake Anthony. If those are on usually they won't notice whatever else, plus then your readings drop significantly. You can pass with a different tune just with an aftermarket downpipe is difficult.

 

Ok, sweet! Thanks for all the advice guys. Time to hit up EQ for a smog tune!

 

hope they let you pass the visual. The smog station on 19th/Taravel checked under my car. But the guy was nice to let me pre-smog 3 times before he sent the actual test to DMV.

 

U don't need cats just passed with grim speed ewg and invidia no cats failed horribly by 50+ then ran it empty thru on my e85 map and pass with flying colors.
