Just a quick note, prop or whatever. My car passed CA smog again, like a new car. For those of you that are on the fence in CA, with all the stringent measures, it amazes me each time that this car runs like it does (wicked) and as clean as it does. The Strikers are amazing, but having a shop that can tune for emissions is the key. Major props to DC Performance, no cheating, it just amazes me. Thanks Dan and Chris.............
