What are the causes of exhaust resonance in Jaguar vehicles?
1 Answers
Jaguar exhaust resonance can be caused by factors such as RPM, sound insulation, and installation. Improper RPM matching: Resonance occurs at idle and below 2000 RPM. The main reasons are improper design of the exhaust backpressure chamber and engine RPM mismatch, or issues with the flexible connection point in the header. Sound insulation and vibration damping issues: Above 2000 RPM or 3500 RPM, the higher the RPM, the greater the resonance. This is usually due to poor car sound insulation, excessively stiff vibration damping hangers, thin exhaust pipe materials, or rough internal surfaces of the exhaust pipes. Improper installation: This type of resonance exists at all RPMs. It is generally caused by improper installation, where besides the hangers, there are other rigid connection points. This often occurs with aftermarket exhaust pipes that do not match the vehicle model.
