in 4th im getting bout 95 at 5500rpm
in 5th im gettin bout 105 at 5500rpm
its still very fast at getting there but seems too slow top end to me.
I think your cat has broken up and is causing a restriction, due to a piece partly blocking the exhaust pipe.......The huge back pressure has then caused one of the EGR pipes to blow off (where it joins to the rubber pipes push-on connection).
Had this happen on my 2 litre Zetec Mondeo with the same symtoms as you describe - lack of performance + exhaust blowing noise.
