crap, sorry I forgot to take some pics, I was in a rush, got home at 9 pm and me and wife up at 5 for a extended weekend.

I have never had to do inspections, but also if it was a problem with the cats I would think it would show up on the emissions test.

I have seen threads of people talking about rattling cats but have never seen anyone try some cata clean, or some people that have gutted theirs, they never said what the problem actually is with this style of converter, if it is the cats building up hydrocarbons on the media clumping together maybe a cleaner, but again a notice in loss of power would be noticed due to the restriction.

wish I could hear what yours sounds like
