1.7 "O" Series Exhaust Downpipes Princess/Ambassador

[Scotty2]

I am needing a new or good set of downpipes for my 1982 Ambassador. Exhaust won't seal at the manifold and the originals are a bit thin and damaged.
Anyone got some? I am going to weld a flexi in them to make sealing them in the future a bit easier. Makes a mini exhaust seem a pleasure...
