Extending air duct in attic?

Me and my wife moved into our home a almost year ago. And since its heating up now. I went in the attic to fix any leaks in the ducts since the house was built in 1991. There is a spot were the duct goes down a chase to hit the first story, its a 2 story house but whoever installed it made it to short and just pulled it over a beam so its almost pinched closed. What is the best way to add duct to it so i can hang it or reroute it a little to get the kink out?

I suppose this duct you mention and that is kinked is a flex duct.
Cut at the kink, add a sheet metal elbow and re-attach.
