The problem
Aggressive sound strategies can create real thermal stress.
Overrun sound calibration changes combustion behavior during deceleration. An aggressive strategy can increase exhaust temperature, accelerate wear, damage catalysts or mufflers, and create noise or road-use compliance issues.
- Requested sound level does not match the hardware
- Existing tune or exhaust configuration is uncertain
- Owner wants a softer burble rather than aggressive events
- Vehicle has faults that should be diagnosed first
