 Heat shield... i think
Another thread from me.
I have a stock exhaust on my ti and it makes a hi pitched vibration noise whenever the engine rpm's increase and its sounds like a poorly maintained civic. Its quite embarrasing when your passing slower cars. But I think it may be a loose heat shield. The vibration sounds like a thin piece of aluminum like the heat shield. I just wanted to know if anyone could help. Thank you.
