Today I raced this guy I know in his mostly stock evo IX (Blow off valve). I have a bosal downpipe and racepipe bolted to the stock cat back and cobb stage 2. I figured he would win but i wasn't sure by how much. We decided to go at it from a 15 mph roll so on three beeps we go, and i pulled on him slightly. He started to pull on me at the end of my first all the way through third. Nothig major, just a slow walk. It was fun. No trash talking afterwards. He said that he was amazed that i car that cost 8k less than his could just about keep up. Just sharing my experience. Enjoy.
