Catalytic Converter Issue, Octavia

Hi all,

First post, so I apologise if this is in the wrong place.

I have an X reg 2.0 ltr petrol Octavia estate. The cat needs replacing but I can't find an exhaust schematic. I've tried looking at spares and it looks as though the cat unit goes right up to the manifold.

Has anyone got an exhaust diagram or can confirm the unit is that big - if so, I may have to reconsider changing it out myself!

Thanks in advance,

Steve
