The wife and I were returning home from dinner last night when I was acoustically assualted by an SS in the next lane (he revved up at me...loudly). I assumed this meant he wanted to run, so I asked him if he had done anything to it. He told me it was stock with a smirk on his face. I knew, however, that it was not completely stock due to the audible impact of his exhaust tone. I told him mine was mostly stock, save for a filter and catback. After the light turned we both managed to get ahead of the traffic and line up. We started at about a 40ish roll and left together pretty evenly, but I steady gained ground on him until we had to let off (more traffic). We then proceeded to do the same scenario at the next light, this time we had a much longer traffic-free distance to open up. This start was more of a 30ish roll with him having a good half car head start (I think he was a little more anxious on the next run). This time I was able to really open it up and just pulled by him with ease. It was a nice run and the driver and his buddy were cool giving me a thumbs up. The wife really enjoyed it too, but she then proceeded to tell me I don't need to install the pulley I bought "...because you don't need it. You just kicked his ass with the stock pulley!" I guess I'll have to get beat before she sees it my way.
