Got mine two years ago on evilBay, I think I only paid about £180 for mine I wish I could remember the make but I don't.
Mine were highly polished and came with gaskets, but mine dont have the little link pipes between the 2 outer down tubes like the originals had, but I can not say I have noticed any difference in the performance of the old girl, she still flies.
Come to think of it I believe I may of bid for them????????? or was that the MR2 stainless manifold? Dunno.
Anyway I replaced all the studs and nuts with stainless steel while I was at it and the down pipes could not have been a better fit, I put a small dab of grease on the gaskets just enough to hold them in place and the down pipes just slipped into cylinder head, with no alignment problems what-so-ever.
I will have a look back at my evilBay purchases see if I can find them.
Nope seems you can only go back till January 2015 on my account for some reason. But I know they were less than 200 quid as I was well chuffed at the time with the price.
You can see the polished finish of the down pipes in the pic below + it shows the lack of the two little links.
