I just found a great car in another state that I was interested in buying, only to realize later that it has a "50 state emissions" no charge option. From what I've read online, this means different computer tuning and cats? I can only imagine how much "California" has messed up this car. I am sort of afraid to buy it now, and it is beyond pointless for me living in a state with no emission checks. I really don't want to buy a new 0 mile car that I can't mod for 3 years because of the warranty, and have to be stuck with that crap on it. Does anyone know more specifics about it? Even if it doesn't affect horsepower, how much worse does it sound? Is the engine bay crowded with all kinds of extra junk in it?
