… in many threads this is always discussed about the technology on and around the exhaust of the new 07 models. Since I am also currently remodeling a new Fat Boy, this is also a very important point for me. That’s why I asked Kess and, for all who are interested, put their answer here in the forum: thank you for your request. Therefore, there is nothing on our homepage, because we can not deliver yet. It is “paper-technically” as far as everything is ready, but w If we don’t sell anything as long as we don’t have the EG ABEs on our table yet. Furthermore, we have to wait for the KATs, which are needed to comply with the EURO III exhaust emission standard. With your model, a KAT comes in every cracker and yes, the plants will then become more expensive. The second thing that comes with your choice, the Shotgun plant, is that we have to provide our crackers with a recording for the Lambda probe. With pots on the original curvatures, this remains more logical for us. The active exhaust system of Harley remains in place, even if the original manifolds remain in place. It continues to work normally. In the case of exhaust systems where the manifold is replaced, the flap and the engine fall away, but we have to simulate the motor electronics that both are still in place, so that no error message is displayed in the amatur. However, we do not intervene in the motorcycle electronics of H-D. We will pre-press the end pots for the original manifold. I hope I could answer all your questions to your satisfaction. If anything is still unclear, just email again. Friendly greeting Kess-Tech GmbH Gerrit Full still a friendly biker’s greeting to Alle BigNig
