Not possible/advisable because of state inspection? Where I live now (Missouri) all the inspection consists of is honking your horn, checking if all the lights and signals work and kicking the tires. So here it wouldn't be a problem...but I am not living here too much longer and I plan on keeping this car until the floorboard drops out from underneath it. How bad are the inspections in some states? I still don't think they did TOO much...it came with emissions equipment (cat, smog pump...) from the factory, so I THINK all they did was mess with the tuning, which can be easily manipulated. I am relatively sure they didn't actually change any parts on the engine. I will try to research it though.
