Seperating exhaust pipes

[Clarkey]

I need to remove my KTEC stainless pipe and put it back together in a new position as it is not sitting right.
I will need to remove the back section from the middle section, but when I put it together I used exhaust sealant and a clamp. :dapprove:

I have tried to remove the clamp and twist, pull, etc but it's not moving.

Anyone have any tips on splitting these two sections?
​Heat?

Tap the box with a copper hammer and a bit of wood to spread the shock across the box.
