I have a 98GT that has exhaust on it and have been running an exhaust for about 6months and have noticed a rattling in the dash, radio HVAC area, that has gotten slowly worse. I'm sure I'm not the only one that has encountered this issue, so what I am asking is what is the common culprit to the issue or where should I start looking?

It is very common every mustang I have ever been in has a dash rattle.

But no idea what exactly is rattling...?

my 96 rattles on the trim piece that surrounds the radio and vents. it loose at the very top and rattles a little bit. I can see mine moving go down the road when I hit rough spots.

That's something that happens when a car starts to age.

mine does that too. i really can't hear it after a certain point between my music and the exhuast. i guess that solved my problem.

yeah completely normal. at least thats the only rattle you hear. i hear noises all over my interior. really gets to me sometimes.

its a combination of unibody and cheap engineering. EVERYTHING in these cars rattle. its just a good excuse for us to get louder exhaust to drown out the rattling :-)
