Have any of you had trouble smogging your Vipers? Specifically anyone in Nevada? I'm curious to see how far you can mod the Viper until it won't pass smog. I'm guessing exhaust is about the limit. Once you throw on some headers and high flow cats or no cats then it probably wouldn't pass. For all of you guys with modded Vipers how do you pass smog? Do you put all your stock parts back on every year or do you find a shop that "passes" your car with some extra money.
