I actually got my hands on two TT225 Exhuast Mani's - This one came with the turbo I bought ... Its brand new!

This is the first TT225 exhuast mani I bought. Found it on E-bay for a nice price. It has some type of coating on it.
You can see the coating is on the inside and outside as well as on the flanges :-( . . . which will need to be surfaced/faced to be usable.
