Re: rattling sound from exhaust
check you cat or see if any pipes are rubbing against anything.

Re: rattling sound from exhaust
this could be so many things.. and i see posts like this all the time. just go under there and push/move stuff around and see if its rubbing anything or you see something broken. might be hitting the heat shields as well.Dave:

Re: rattling sound from exhaust
heat shields are a good possiblitly. do what david said, shake/move your exhuast and see. heat shields are the most common issue.1998 bright red camaro ,M5 ,Y87 ,stock<br /><br />Originally posted by Rune:<br />If it smells like a turd and looks like a turd, chances are its probably not a candy bar.Comment

Re: rattling sound from exhaust
Yea, most likely will be heat shields or your cat. On my car it just happened to be the cat, which for me worked out because I got a hiflow cat and 3" piping all the way back out of it :DOriginally posted by loserComment

Re: rattling sound from exhaust
Right now as we speak my exhaust manifold heatshield bolt has broken and it rattles really bad when i start it up in the morning, at idle, and then just cruising.Comment

Re: rattling sound from exhaust
it could be the heat shield, a loose hanger, or you may need to add another hanger, same thing happened to me, and now that its cold it makes a little noise too, i just think its due to the cold and it being metal. but in the summer it sounds fine.Comment

Re: rattling sound from exhaust
ya. for the first little while, the car is fine, then once it gets hot it rattles. i still cant find why. i checked EVERYTHING, and havent found one thing wrong, except that maybe it isnt a true dual exhaust as i hoped. (bought the car used)Comment
