Default Cat to Mid pipe Gasket Removal?

Put a new cat-back on my car this past weekend with the spring kit, etc. I was not able to get the metallic cone gasket off the cat side and it is leaking. How do you get the gaket off? Heat? BFH?

Thought about a grinder but that was the reason I needed the cat-back.

Edit - Sorry, it's a 2001 Legacy Wagon if that info is needed.

Any ideas would be appreciated. Thanks

Ken

I stabbed at it for a while with a flathead screwdriver until it started to come apart. Then I used Vice-Grips to yank on the metal mesh inside until I finally gave up and came off.

i took a chisel to mine with a hammer....pried it off of the cat after a few good whacks to get it seperated from the cat.

Thanks folks. Was afraid that was what I needed to do, was just hoping that there was an easier way.

Time to break out the dead blow hammer and cold chisels!

Thanks again.

The exhaust is either mild or stainless steel. The gasket is rusty layered lead/metal. Don't worry about it.

Heat is your friend.. the hotter you can get the pipe that is holding onto it, the easier it will come out. dont use too much heat though, a good propane torch on full should be fool proof and do the trick.. O2/acetylene could make a hole real quick if you are not careful.
