Poll: What kind of exhaust are you running?

[Brookland27_imp]

The bikes onboard ECU can compensate for small changes in flow (saying "backpressure" makes it seem like that's what the motor wants.. it doesn't) most people get by without retune fueling when simply putting on an open flow silencer even. I can tell you from experience though that the bike will run noticeably lean <5k revs without a power commander. I installed the power commander with the supplied stock tune and it runs so much better in the commonly used power region. I actually think the sound of the pipe actually just accentuates or makes more apparent the lean state the bike is delivered with. When you cant hear it you just feel flat. As far as changing the intake is concerned that is another ballgame but the motor can only put out what it intakes so freeing up outflow doesnt require any chang e in intake only fueling. But that's another thread .
