OAK hook up

Ok so over the weekend I got the new pellet stove in the house and on the hearth. Today the vent piping came in the mail and before I had to go into work I quickly took all the pieces out and slapped together looks like its all going to work! Well except the OAK is a bit too short. 6' worth of metal flex pipe came with the kit and I'll need 9'. I've looked at several online places and can't seem to find a place that sells just the pipe and a coupler? Any suggestions? Also I read if going over 6' its recommended to go up to 3" size pipe. I cant seem to find 2"->3" adapters either, though I'd hate to have to buy another whole kit but I will if need be.

Now that I have everything including pellets, I hope to have it all hooked up and ready to run in a few days, except for the issue with the OAK not quite long enough. So if anyone has suggestion on where to find these parts let me know, thanks!

Seems kind of silly with how popular these OAK's are (and even required in many cases) that you can't buy the parts without adapting drier vents and auto parts lol.

You can buy a 3-2" adaptor off amazon for about 5 bucks.

Though I'd really love to just use the kit I got and not have to buy a bigger 3" wall plate since I already have one, but I still can't find parts on amazon. Got a link? I've searched for adapters, reducers, etc. See plenty of 4" to 3" reducers but not 3" to 2" except for stuff for plastic hoses and shop vacs etc. Also don't see a single listing for 2" aluminum ducting if I were to use the parts I have and just extend a little further.

Also do you insulate it somehow? Seems like running sub-freezing air down thin aluminum duct is a great way to bring some cold into my living room.
