I've finally got round to fitting my manifold I bought ages ago. I was sure it was a Toyosports one, but after digging it out from the back of my garage I'm sure its not.
Any ideas what it is, or is it just a generic ebay one?

The 2nd hand Toyosport I had (briefly) had a plate with a chequered flag logo and "toyosport" stamped on it

Yeah, I was positive mine had that. Maybe I've just seen it on others and wrongly presumed!

My Toyosports bought off ebay in July last year has the flag logo and Toyosport stamped on it.
That one doesn't look like my Toyosport, that's all I can say. Mine doesn't have any supports on the midpipe end or any mounting points for the heatshield.
Take a metal ruler to the head plate- if it's straight it's a good one, if not it's a JHM (I think)
It looks very much like the one I had from America, better than the toyosports, the heat shield brackets never lined up very well though so that would be the tell.
Edit
Rumour had it, it was a che top speed one
The Hamish/Garage 59 one I had had the same square section bar welded as the heat shield mounts with different sized threads tapped in them.
It looks like a typical eBay manifold, but the problem is there have been many different manufacturers with differing quality and features. Some were mild steel, while most are some grade of SS. Some used stamped manifold flanges, and some used a thicker plate flange. Some had a proper recess at the bottom for the OEM "donuts", while others just used a flat flange and gasket. Some people consider the Che manifold as the best, but over the years they have sold many different versions.

The one common characteristic is they all seem to have poor fit for the heatshields!
I have bought 2 for 2 different MR2's and just went with the cheapest (stamped manifold flange). One key to header survival is to use the FL cast lower mounts, which are much stiffer than the PFL stamped mounts and use OEM gaskets. One has been on one car for over 10 years with no issues.

I thought the heat shield was going to line up but checked again and it's just off!

It's a solid flange and also has recess for the donuts!
I also have a facelift so the cast mounts will be going back on.
Now just to wrap it and get it installed!

Sounds very much like the che one then.
If it is che, Mwr still sell em for about 280.00 dollars. You might have a bit of a bargain there.
The Hamish lower shield mounts were useless, didn't match the holes on the shield, I ended up drilling new holes in the shield and trimming around an inch off the top so the upper shield would fit over it.
