Thanks Boxtsaboy,

I'll check the clamp. I was thinking it was the baffling inside the muffler because the exhaust tone alternates from sounding very nasally or froggy to sounding deep and smooth like a porsche should sound. I'm envisioning a piece of metal inside that's shifting changing the flow of air through the muffler. But even if it's just the clamp I'll still swap the muffler. It has about 80K miles fewer on it and it has the dual tips. And since I've already swapped out my headers and secondary cats with performance headers and secondary bypass pipes the muffler can be the only culprit left.

I used to have a rattle at idle on my muffler too, and at first thought that the muffler had a loose piece inside it, but later traced it to a loose clamp that connects a U-pipe from the cat to the muffler. If I pulled on the u-pipe, I could tell that it was loose and would move. After fixing that, no more rattle.
