2017 S exhaust rattle (video link)

Interesting, my 2017 v6 rattles but no where near as much as that.
A good test on mine is to squeeze the shaft axially and the rattle gets loads better.
Also without the car running you can bash the silencer with your fist near the valve’s and you can hear it….

Hoping someone can remote diagnose. My exhaust started this rattle in the startup that goes away after the idle drops to norm. This started abruptly and have heard nightmares about the valves but hoping this is a loose hanger or shield rubbing. Just took it out of winter storage. Only has 23k on the clock so let the maintenance begin. Any thoughts?

This is a totally unqualified opinion although I seasonally drive my F-Type V6. Get it up on a lift and take a look. It could be temperature expansion/contraction making something lose its clearance. If it didn't do this when you put it away, could some critters have left you some goodies in the exhaust system? Although one would think that would blow out when you started it. I had a cat convertor go at one time in a different car that left some debris in the muffler that rattled for a while on startup. Anyway, these are simply guesses. When you find out, please share the outcome with the rest of us F-Type owners. Good luck, hopefully it won't be too expensive.
