I would like to replace the section then mess about with the flexi. Whats the part number if known and best place to buy it. Also is the box it leads to the cat and whats a decat do. Thanks

Cheapest option is to replace the flexi joint.

I got one on my ex-Vec-C and had a local garage chop it out and weld a new piece in.

And yes, sadly it is part of the Cat Box, hence the chepaer fix.
