If you own a car in Nashville and enjoy driving with an aftermarket exhaust, you might have noticed drone noise during highway cruising. This droning can be distracting and diminish your driving experience. Fortunately, there are effective ways to reduce this noise, especially with an axle-back exhaust system.
Understanding Drone Noise in Cars
Drone noise is a low-frequency sound that occurs at certain engine speeds or RPM ranges. It is often caused by resonance between the exhaust system and the vehicle’s cabin. Axle-back exhausts, which replace the rear section of the exhaust, can sometimes increase drone if not properly tuned.
Strategies to Reduce Drone Noise
- Install Resonated Tips: Adding resonated tips or inserts can break up sound waves and reduce drone.
- Use Sound Dampening Materials: Applying sound deadening mats inside your trunk or rear panels can absorb vibrations and reduce perceived noise.
- Choose the Right Exhaust System: Opt for an axle-back system designed with drone reduction in mind, often featuring built-in resonators.
- Adjust Exhaust Mounts: Upgrading or repositioning exhaust hangers can alter resonance frequencies and diminish drone.
- Consider a Tuned Exhaust System: Custom tuning or adding a secondary resonator can significantly minimize drone at specific RPMs.
Additional Tips for Nashville Drivers
Since Nashville’s roads often involve highway driving, focusing on solutions that target high-speed drone is especially beneficial. Regularly inspecting your exhaust system for leaks or loose fittings can also prevent unwanted noise. Consulting with local exhaust specialists can help you find the best setup for your vehicle and driving habits.
Conclusion
Reducing drone noise in your Nashville car with an axle-back exhaust is achievable through a combination of proper system selection and installation techniques. Implementing these strategies can improve your driving comfort and enjoyment on Nashville’s scenic highways.
