Can you still get the under-car twin cats for the XJR6? The ones just before the back boxes. Only a connecting pipe on my rear cat has cracked right through.

I suppose it could probably be welded up but in my experience once welded they'll usually crack again in time, near the weld. Better to get a new part if possible.

 

They appear to be NLA from Jaguar

Aftermarket, perhaps?

My recent Exhaust manifold issues on mine caused me to research what is out there at least for the U.S. PartsGeek website has these for replacing the rear cat. Looks like a redesign of two smaller cats rather than one big one if i am understanding it right.
