This phenomenon is most noticeable during steady-state cruising, where engine speeds coincide with the natural resonant frequencies of the exhaust system and vehicle structure.
- Frequency Amplification
The removal of the intermediate sound dampening device can lead to the amplification of specific exhaust frequencies. This amplification occurs due to the elimination of a component specifically designed to attenuate sound waves within a targeted frequency range. The absence of this attenuation results in certain frequencies becoming more prominent, leading to increased resonance. For example, frequencies around 2000 RPM might become particularly pronounced, causing a noticeable drone within the cabin.
- Cabin Interaction
The vehicle’s cabin acts as a resonant chamber, capable of amplifying certain frequencies generated by the exhaust system. When the exhaust system produces frequencies that align with the cabin’s natural resonant frequencies, the sound waves can reinforce each other, leading to a significant increase in perceived noise levels. The removal of the intermediate sound dampening device can shift the exhaust’s frequency profile, potentially aligning it more closely with the cabin’s resonant frequencies and exacerbating the drone effect.
- Material Vibration
Exhaust resonance can induce vibration in various vehicle components, such as body panels and interior trim. These vibrations contribute to the overall perception of drone, as they generate secondary sound waves that propagate through the cabin. The intensity of these vibrations is directly related to the amplitude of the resonant frequencies produced by the exhaust system. The removal of the intermediate sound dampening device can increase the amplitude of these frequencies, leading to more pronounced vibrations and a more noticeable drone.
- Mitigation Strategies
Various strategies can be employed to mitigate exhaust resonance following modification. These strategies include the installation of resonators, the use of sound-deadening materials within the cabin, and the adjustment of exhaust routing. Resonators are designed to attenuate specific frequencies, effectively reducing the amplitude of resonant sound waves. Sound-deadening materials can absorb and dampen vibrations, minimizing the transfer of noise into the cabin. Modifying exhaust routing can alter the system’s frequency profile, potentially shifting resonant frequencies away from problematic ranges.
Exhaust resonance is an unavoidable outcome, but the level of resonance can be managed through appropriate selection of components and implementation of the discussed strategies. Modifying a Dodge Challenger can be a complicated choice of what is better, and what is worst for the modification.
