Default Reasons for real quiet exhaust?

Ok for some reason today when I went to drive my car the exhaust was a lot quieter than usual. The setup up is LPP LT's and ORY, and the SLP dual/dual muffler with the CME so its not the loudest to start with but it is usually louder than it was today. Like you could hear it the exhaust moving through the headers like normal up in front of the dash but then nothing out as far as sound out the back like normal. Any idea's on why it would that much quieter? I guess its time for custom true duals into the CME...

Also, I took the brace that goes under the ORY and driveshaft because it was vibrating too, but I still have to fix the annoying vibration from it hitting against the lower motor mount bracket.

if you want your brace back on, just space it out with a bunch of washers. I did it, it works. There is always a way to rig something up.

The dual/dual has been on there for the life of the car, 97000 miles now. And I don't think I've lost a cylinder, the power seems fine. It seems like I would notice running on 7 idk though. It sounds fine at idle but when I put it in gear it's like almost silent. It seems raspier at wot too...
