    Need some help before I decide to go to a shop or dealer to figure this out. First off the car drives and preforms perfect. no issues, but as I'm driving I get a vibration noise coming from the drivers side rear, once I exceed about 3000 - 3500 rpm's its gone. I've checked the brackets on the tail pipes they are all tight. I was able to tighten down the medal shields that go around the cats. I was told that my next try should be a pair of pliers and bending the flange on the cat covers to make sure they are snug because they could cause the noise. Anyone have any suggestions????. Its surely is the exhaust system Thanks. John

    Would it be possible to have a friend rev the car to the spcified RPM so you can poke your head around there and get an idea of what you are dealing with, or does it only do it under load?

    If it happens while sitting still, it may be a good time to invest in an Automotive Stethoscope to help better track down the noise. Do you notice it when it is cold, hot, or does temperature not matter?

    More so when its cold, but it goes away a bit when its warmed up. Load does not matter. Thanks.
