I have a 6" SS insulated liner, will I have creosote buildup problems if I put a 18" tall metal flue extender on top of the chimney? Being uninsulated and directly exposed to air makes me curious.

Attaching to one of these:

The reason:
I am in the process of re-topping a masonry chimney. I took it down below roofline and am building it back up and it is going a lot slower then I would like, and there is bad weather coming in followed by freezing weather. By using an extender means I can make the masonry chimney 18" shorter which is about a days worth of work for me.
Found an top plate adapter to convert between flex SS liner to class A pipe, it slips into the inside of the flex liner and attaches with screws then the class A side has the twist lock that goes on top. The masonry chimney with 38' of SS flex will be up to the roof ridge then the class A pipe will extend the remaining 2'.
The ridge of the roof is 50' off of the ground with good 12/12 roof slope, if I can save a day (2' of brick) I will.

Got a link? I've looked and not been able to find that.
Here's ICC's Excel version:

Thanks Dak, that looks pretty slick. Doesn't look as though one can purchase through that site though.

If this is the product, I don't see there being a way to connect the single wall to it.
There's a corrugated extension that comes off the bottom of the plate & that fits inside the SS liner. The liner is secured with to that extension using "Zip" screws...I think you can see it better in the EXCEL version...
