Hi I have a tubular exhaust manifold suitable for an 1.8t Audi engine conversion. It has a 4 bolt Garret type flange suitable for a GT or T3 style turbo. Also has an external wastegate outlet which you could use or blank off. See pictures of it fitted to my car.
It was taken from my own car as a I changed my turbo setup but ideal if you are doing a conversion.
Has has a small repair to some cracking near the flange but overall excellent.
