As Ruairidh suggested I checked out the parts list illustration
and could see how short the original  integral tailpiece was.

As a Cup and also a “special” my Cherry Bomb is
Very unoriginal but will make a nice sound!
I’ve got one on the tail end of my TR3A system :-)

I found an extra steel manifold flange bought a while ago
and using this as a spacer, plus the gasket etc. It
Dropped the old exhaust down a bit, plus
I put the pipe in the vice and squeezed some gentle bends in it
Plus ovaled it where it passed under the hoop.

Sorry hoop but I ground about 1/4” off your bottom edge.
This gives a 1/4” clearance there.

As the engine, and exhaust are bolted solid to the chassis
there’s not much possibility of flexing or rubbing anywhere?
There’s still the radius arm clearance, is 2” sufficient? At the intersection point.

So may just add a short tailpipe and get the one pipe joint
silver soldered or brazed, though the join is far enough away 
from the exhaust manifold to perhaps use plummers solder?

Will try brazing first I think.

Thanks to those adding ideas.

Regards
