Default Pacesetter y pipe

So my 95 turbo lt1 build is 99% ready to go but my y pipe on the driver side where it is knotched for the frame is hitting pretty good. Now that the pipe has been installed and ran its not coming off to easy. I have something wedged inbetween the pipe and body right now but of course the vibration is killer. I have tried to pry the pipe with heat and the mother of all pry bars bit not much change. Any other suggestions?

I had been thinking of doing what I need to pull y pipe off car and then using my press to squeeze the knotch part more but its a bitch to get the pipe off now to do this?

Mine did that and I wedged Something in there and drove it for awhile and after 1k mikes I took it out and no more hitting. Mine only rubbed under acceleration now it's good to go. Must have formed it from the heat cycles

I had a big chisel in there I removed it today and seemed much better than before. I put some titanium header wrap on the pipe as well for the turbo. Now im going to drive it under heavy load to see if it hits at all.
