Yeah tireburner is right. Anything that doesn't up the compression ratio, alter timing, or fuel curves will be fine w/ 87. For those of you who run premium in your cars your just wasting money and confusing your EEC. You actually get worse gas mileage when you don't run the recommended 87. Those of you with Snakes have to use premium though but I'm sure you figured that one out for yourself because it says so on the instrument cluster. And about the silencer, people can say what they want, it does add power. It tends to add about 3 rwhp. I definitley noticed a difference when I pulled mine. Plus it makes a cool gulping sound when you crack the throttle. Not bad for free mod that takes about two minutes to do.
