Scrapped - Opel Manta A series Exhaust

Going in the bin is this exhaust section from an Opel Manta A series which I had been keeping it as a pattern for future reproductions of exhaust systems for the Opel Manta, but that won't be happening now.

UK version of the Opel Manta A series exhaust
The exhaust on the UK version of the Opel Manta differs from the European versions because of the compromises necessary to rework the design to suit a right hand drive vehicle.
The downpipes have to merge much closer to the exhaust manifold than on a European car, in order to clear; the steering column, clutch cable and brake servo. Whether or not this restricts the flow and reduces horsepower is a moot point.
To complicate matters further, automatic variants of the Opel Manta A series require a couple of extra kinks in the downpipe in order to clear the much bulkier gearbox. I have even heard that on the last of the Opel Manta A series, produced from August 1974 onwards, had a different design of engine mount, moving the engine slightly further forward and requiring a marginally longer front pipe.
