Exhaust Tools INC does make a tool to seperate the pipes without
damaging either....I have two of them....(one for 2 to 2 1/2 inch
pipes and the oter for 2 1/12 to 3 inch pipes)...
They work very well and do not damage either pipe...
Unfortunately I believe the cost of the tool(s) would exceed the cost
of replacing the parts.... I restore old cars as a hobby and I have
a need to remove old exhaust systems enough to justify owning the
tools (thats honestly questionable)...
I think you are going to have to bite the bullet, and open your
wallet, ....
I do not know if the manufacturer even has a web site...just a small
outfit that was selling these tools at a swap meet in Hershey Pa
and Carlisle Pa few years ago...
BTW: I hate exhaust work...!
