Can anyone recommend the easiest way of cutting a double wall stove pipe?

I have redesigned my stove pipe to give me further distance from combustibles by putting a 90 degree elbow and a “T” for easy cleaning during the winter. However by adding the 90 & “T” the straight piece of stove pipe is now to long and needs to be cut to proper length.

MOST that i know of you can NOT cut double wall pipe.

switch it out to a shorter pipe and a adjustable slip.
This will make it easier to take it apart to clean out that 90

Why not use 2 45 deg for an offset. BETTER DRAFT

Yea, what Rob said.

How would you connect the pieces once you cut off the twist lock connection?

I would guess that he is talking about black inside double wall stove pipe . The stainless steel double wall stove pipe with the lock tabs should not be cut.

You are correct the black inside double wall stove pipe is what I have.
 
and as stated above, you can not cut it. You cant cut interior or exterior double wall. Follow robs advice and get a couple of small adjutables

Sorry Hot Rod !

You must be one popular, uh, Guy!
 
Just as a side note . I stated "How" to cut double wall pipe . Now if it "can" be cut and installed i do not know this information like some of the others here do . I used telescoping double wall pipe for my install in my home . I used single wall black pipe for my shop and it could be cut . I'm not saying the double wall inside black pipe can be cut . I would take any good advise from hearthtools and or MountainStoveGuy for custom install information.
