Has any one tried to get their WRX to pass emissions with a TurboXS exhaust? I don't even know if they do a sniffer test on these cars. I have a cell mod that is not on the car but will that be enough? I will keep the car idling until as long as possible to keep the cats warm. My setup is the "stealth" and I can always put the original exhaust back on but I don't want to. I will have a TurboXS utec soon, can I load a map that will allow me to pass emissions without potentially damaging the car, something just for the test? All knowledgeable info will be appreciated.
Thanks

 

Search on the web too lots of info about passing even a CATless car. Fuel additives help A LOT! WRX's with one CAT can pass with the right fuel.
