pulled the car outside the other day. its been alot cooler here (30-40degrees). I have noticed a weird new sound from my setup. I am running kooks o/r headers with bullet resonators along with corsa extreme. It almost sounds like something could be loose or broken in the muffler. you can really hear it when you let off. It's a metal flapping sound almost. Sounds like air is leaking almost. Think its normal with cold weather? Or could something be broke? the car is warmed up in the video.

Check your clamps.

Is yours an older version of the Corsa? I know earlier variations of the exhaust had issues with the weld breaking on the adapter towards to cats.

After reading, you have the performance connect since you are running headers, don't think those had any issues.

Maybe packing came loose in muffler?

It does sound much more metallic and raspy in the cold weather. You may have to do a relatively long drive to get the pipes hot enough to hear a change.

Mine does the exact same thing and has nothing exhaust in common with yours. Kinda the same rattle tinny whatever sound the 5.0 just makes. Bugged me forever, but I’m over it.
