Help Seperating Exhaust Pipes
Oh and I really don't want to cut it up.
If it's still stuck you can either gently hammer it off (place a small 2x4 on the pipe and hit the wood with a hammer) or heat the slip fit pipe with a torch. The cheap parts store propane torches will work, but you'll need to heat the metal for a good 20-30 minutes and even then the heat will be barely sufficient. An oxy-acetylene torch will make quick work if you have access.
Last resort would be a Dremel. Cut a small slit along the slip fit and see the first posted method.
So I have a perfectly good Flowmaster Catback ready for sale.
