I wasn't looking for more horsepower (directly). I put the exhaust on it so I could hear the bike. I like to watch the road when I ride and hearing the exhaust allows me to shift the bike better. I didn't want an excessively loud bike and have been happy with StainTune exhausts on previous BMWs. It works as expected and I like it.

I didn't notice any substantial improvement in HP or Torque. The 5000 rpm dip is there with the stock system also. I liken it to a turbo - get it up above 5K and it takes off. As an extra benefit, the StainTune is much lighter than the stock system.
