strange noise i bought my t/a a few months ago and about two weeks after i bought it, it started making this weird rattling noise from the front of the car, some people told me that it was my cats so i had them removed and i still have the same problem, does anyone know what this could be?
Front of the car is pretty general, can you narrow it down a bit?
There should be some tubes coming off of the exhaust manifolds. The one that comes off the driver side has a matching one on the passenger side. This is the AIR system, which has some check valves that like to rattle.
Try to localize the sound and get back to us. Also, what are all the mods to the car? What year is it?

After listening more to it, it sounds like it coming from right under the car somewhere near where my cats should be. The only mod i have on so far is the SLP lid and K&N filter, and its a '98.

More info. If its just on start up for a second or two, then clears up, and you're an A4, I'd say your converter is loose. Otherwise
without more info..

You can jack the car up and check'em yourself but its a bitch to tighten them. You need to lock-tight them too.
Other than that, jack the bitch up and with your hand touch everything you can and try to find something loose or something that flexes enough to touch another metal part. (ie: loose exhaust)
