For a couple of days before you do the deed, keep spraying plusgas on them liberally.

Really makes all the difference

Whats plusgas will wd40 do the job?

Plusgas is err............ Plusgas exactly what is says on the tin.
WD40 won't do it, not good enough.

Hi Raymienits, seems you might be able to help me. What are the signs of a failing cat on the 2.2, any distinct noises/codes etc...?

[tunnie]

before you go taking anything to bits, why does cat need replacing? Are we actually talking about the cat, or the flexi join after it?

[PhilRich]

As already said... give us some more info on why you feel the
need to change the the cats? Bear with us, you could save a lot of money/ effort!?

[Erzy]

Can you let me know the symptoms/if any of a failing cat or pre-cat on the 2.2. ?

Sorry for taking so long to get back on this work shifts. The reason I need to take it of is that the flexi joint is burst and when I had to replace the mid section on the exhaust the bolt snapped so had to drill it out and unable to get it airtight using a nut and bolt. Was told on here that I could replace the flexi joint but cat would have to be removed to have it welded all the way round. I Maybe wrong Only guessing.

Car driving poorly and very noisy underneath. All other parts of exhaust renewed in the last couple of months so no corrosion there.

Had my flexi done last week. Took car to a custom exhaust outlet. They done it without removing cat. Unbolted the cat bracket and supported it on single acro prop type stand, cut flexi out, welded new one in job done

Assuming they had a car lift for that to get good access? Can't see that being done on a driveway 

DIY approach is exhaust bolts off, 4 bolts where exhaust bolts onto manifold and finally the cat bracket, flexi costs about £15, and as mentioned needs to be cut off and have  a new one welded on
