I haven't seen any reviews on these. Anyone on here run one?

It looks decent, no clue on flow. If I did get it I would polish the casting marks off.

Looks like a knock off of the hks mid runner cast manifold.

I figured as much. How well do the hks manis work too?

I would expect that to go 800 HP, you'd need a full mandrel tubular manifold.
I would think you could get at least 600hp outta the cast unit, though.

600 is decent, I guess I can buy it and find out i really want to get my car on the road, though i havent cheaped out on any parts on my build. My friend wants 1200 to build a custom ss manifold. He use to work at full race now works at AFI a local AZ shop. But if I can get a decent amount out of it maybe more if I open it up and polish the runners I'll settle for that for now.
