New RE Amemiya exhaust
Interesting design, looks like something Odula has. They are claiming 5 - 10ps increase. Wonder how it sounds.

Edit: looks like a new manifold too. But no other info.

I wonder if the opening is the same as the old Amemiya or bigger.

what opening are you talking about, the tube diameter? What's yours? OPening up the plate ports serves no purpose unless you open up the housing ports too.
EDIT: upon further review they made the two back pipes pipe longer to try and equalize the length, the thing is that without port timing overlap like the Renesis has it's not going to do much but run up the cost, I can't tell if the diameter is the same or not

Anyway an update: On dyno run an 8 6mt Cosmo (the same like yours Hi Pow) which showed 222 hp with cat exhaust and revi+ram air, after the install of the header and pulleys I am talking about and with nothing else on it, showed 235 hp. No ECU tweaking. I was not present but I trust like family the tuner that told me that. As for pics flame me because I deleted them by accident last night so now I have to find them again.

Also in rx8club.gr a guy did the whole amemiya package, intake, exhaust, header, cat and from 180 hp (Hi Pow) showed 224 hp. No ECU tuning. Now he will install the new HKS piggy supposedly coming out in a few weeks with porting and we are anxious for the results.
EDIT: The weight of the SCOOT Sports header is 5,945 kg.

The cat/mid-pipe protrusion that the crushable ring gasket fits over is 2.625" diameter, so it at least has to be that diameter because that projects into the header opening. Making the header outet diameter larger will only work if you intend to have a larger cat/mid-pipe inlet, which would then be a custom match fit only. It will actually hurt flow to have the header outlet diameter larger if it feeds into the smaller OE size cat/mid pipe inlet.
I'd still like to know what diameter tubes yours has, you can PM if you'd rather not say publicly.
