After going through old exhaust tick posts, I have read that the main cause can be at the 'ball and flare' union. I've put hi-temp RTV on it before to try and seal it, but to no avail. I also read that you can use Great Stuff to seal it. It also sounds like it is coming from the catalytic converters. No rattles when you tap them and couldn't feel a leak.
Would regular Great Stuff work or is there a hi-temp version?
