Help identifying 8" double walled chimney class A

[jadam12]

I cannot determine the brand of double wall class A chimney that I have coming out of my roof. I need to make it higher to meet code and create better updraft.

I think it's dura tech but I'm not sure. The chimney cap is aftermarket. Nothing written on the chimney or box.

Can anyone identify the brand?

Rust holes on the outside. That means water has gotten into the insulation reducing it's effectiveness.

I think duravent but I am not sure

Lock rings look just like the new Duravent SS I had installed in December 2022.
Agree the upper 4' section should be replaced if there are any penetrations through the oputside pipe.
