Hello Everyone,
Has anyone had any issues with noisy heat shields? I have been noticing a noise coming from what appears to be the heat shields when the car is riding down the highway or even at an idle in park. The noise seems to get quieter when you accelerate but when you hit speed it gets louder. When you start the car up and it is cold you also hear it. If anyone has ever had this type of issue please let me know and what did you do to fix it.
