I have a 04 Galant and there is a rattle coming from the area of my catalytic converter. I brought it to the dealership and they said they can't find anything???? Anyone else have this problem?????
:beer:

if its the cat, its probably coming apart on the inside. does it intensify with accellaration?.. if so.. youll need a new one.. or just take it off and dont run one lol.. i dont know how your emission laws are where you live or anything.

There may also be a small rock in between the heat shield and the cat, but the cat breaking in is the most common cause for annoying rattles.

I have a 03 Galant, and when I went in for a oil change my mechanic pointed out to me the heat shield coming apart. I was completely unaware of the rattle that it was making. The outcome was he removed the heat shield. Thats it :57: I think you cat is fine its probably a loose heat shield. :thumbsup:

yes.. i have the same problem... but dont know where the sound is coming from and its not consistent, i took it to the dealer..he could not find it. dont know what to do now. I think mine comes from either driver door or windshield area.. mostly i will get on bumps / railway tracks..etc... any ideas what it could be..?!?!?
