loose bolt? i havent had time to check yet. just looking for ideas

 

sounds like a broken baffle in the muffler I've got the same rattle. does it rattle going around curves?

 

i havent noticed anything, but i havent been listening for it either.

 

mine rattles real bad when turning left??? but it sound very similar

 

do you have the stock muffler? because i have a 2k1 and i dont remember if that has the little flap inside that opens with higher back pressure or if that was 02+. could it be that

 

I do have the stock muffler but it is 9 years old. and the rattle started about 6 mouths ago.

could be I guess but has it alway done it? if not then I don't think so. how old is the muffler?

 

i just noticed it in that video which was taken a week ago, it didnt make that noise a few weeks ago when i made anothr vid.

i think i can faintly hear it after the 2nd rev right at the end.

 

Bingo!!!!!! it sounds like you found it. It drove me nuts I took it to the muffler shop that put my Y-pipe on. I keep telling them they cause my exaust to hit the bottom of the car somewhere. we went around and around until we found it. Just a broken weld inside the muffler.
NTW my has gotten worse everyday. I'm still looking for the right muffler sound
