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.

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

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.
