i noticed my rightside muffler rattling back a while ago... which was a couple of months after i bought my GT. it's very subtle, but noticeable at idle. anyone had the same problem or know what's the issue? should i just tell the service center to replace the muffler altogether?
I had the same noise. You can hear it when the car is on idle and you step out of it. I can't hear it inside the car. The noise is on only once in a while, not everytime. I asked the dealer to check it out, but he couldn't find any problem...
