Yeah. In the video you really can't see the speed, and I couldn't open it up all the way there. It was around 3/4 throttle on the fastest pass on there. I actually did get the chance to see what it could do today, because I went a few blocks down to a street that I thought may be long and flat enough to see what it could do. Just barely! But I did get it to a point where the engine just plain topped out, and boy did it! Even with a lean setting with the stock pipe, it won't get to the RPM's that it does with this one.
