I posted a while back about a crack in my headers, I put new shorties on, and it runs so much better, I had to have been losing tons of power before, because she screams now. I did an oil change too, with the Q horsepower and she runs like butter. I drove from Salt Lake, Utah to Las Vegas and it ran great the whole way! I've never felt a car that drove this smooth. It was like riding down a hill of butter I'm slowly but surely fixing all the small issues with my car. Next, I'm going to slap a blower or put a 75 shot on, but most likely the blower.
