I have a rattling noise while accelerating or decelerating, i do have an ark exhaust but this started out of no where, i looked under the car and this is the only piece i could find that somewhat shakes when i touch it, should i squeeze it with a wrench? Thanks

In your videos, those appear to be the primary catalytic converter heat shields, however in the video you didn't attempt to cause them to make noise?

You said you have an Ark exhaust, did you get the version with the high flow catalytic converters in the secondary position? My money is on that, those cats fall apart internally and then the monolith is simply in there just rattling around instead. Happened on mine after an extremely easy-driven 250 miles after install.

I have a rattling issue on my tsudo midpipe too. It seems to be coming from the front flange but neither I or am exhaust shop could find the issue. Any ideas?
