CBR 125 Downpipes stuck... Help?!?

[pluckthechick...]

Hey guys,

A little bit new to all this stuff but here goes-

Just went to replace the rust stock exhaust from my CBR 125 RW-6 with a nice new shiny one. Trouble is, the old exhaust kind of fell apart it was in such bad nick, and the top of the downpipes is stuck into the cylinder head.

Tried WD-40, heating with a blowtorch, tapping with a hammer, tapping a chisel between the manifold and cylinder head to try and loosen it up but the thing is stuck there like it's welded on.

Anyone come up against this before? Any ideas or hints?

Would really appreciate the help cause my bike's been out of action for a few months now.

If you can get a small chisel in without damaging anything try 'folding' the pipe inwards.
