Wondering about liner myself. I just installed an insert I bought from a guy. At the last minute he remembered he had a length of pipe. It was 2-4ft sections of single wall ss and a 5ft piece of flex ovaled all riveted together and in good shape. Being on a budget and anxious to get it in, I used it. Plus the ovaled flex just slipped past my damper so I didn't need to cut it out, worked perfect.. Thing is, not sure if it is really the right stuff or the best set up.
 
What kind of stove is this? If it's a pre-epa stove it may work just fine. If it is an EPA stove that probably is too short for a good draft.

Does this go all the way to the top of the chimney or does the SS pipe terminate inside the chimney? If it terminates inside, then cleaning will involve removing this liner and sweeping not only the liner but the clay flue tiles of the chimney as well which will be a PIA. Also, that original masonry chimney would need to be in tip-top shape (no cracks in tiles, clearances to combustibles met, etc)

From the Top:

I have a Regency r16 built in 91. I picked up another foot of ss single wall in order to make it out of the chimney for a total of about 14ishFt. I just need a top plate to finish. Chimney is in good shape not cracked anywhere, well built brick chimney with two separate flues both 13x12.5, one for basement fireplace one for main floor fireplace. Been reading alot about insulating the liner and understand it is good for keeping creosote from building as quickly. But when is it absolutely necessary?
 
Not absolutely necesssary if the chimney is in good order. I would recommend you make a block-off plate for the setup to block the air from traveling up and into the flue.

Have thought about that. Whats a good way to set that up? Read about guys using the old damper they cut out, but I didn't cut mine out. what about something simple like some ceramic batting, I have 12''x 24" piece coming and I really only need 6"x 24".
 
Yep, roxul insulation rock wool, would work just fine for this. Many also use a metal plate but anything is better than nothing.

That's what I'll do then! Thanks for the input.
