It is made by MNR, sold as their Race manifold (4-2-1) and was made for a 5VY yamaha R1, but id have thought it would fit other bike engines with the same size exhaust outlet, as it is easy to modify for the port spacings as each of the individual outlets are push fit into the collectors
It is stainless pipework with mild steel flanges. It has been used with exhaust wrap on it so it looks very discoloured and the colour of rusty mild steel, but should polish back up with some elbow grease
asking £50 for it
