J's Racing
Thanks guys 
Only test I'ce done with the ETD is at idle - the engine seems to be smoother with less vibrations - also the gear knob has little or no vibrations which would most deifinitely aid spirited driving.

I shoould have checked but didn't get round to it. But it weighs a lot less than the stock manifold.
BTW - the Amuse R1 may be the lightest but the JS yields the most gains

Somebody dyno'd the Amuse and it gave the same gains as the Mugen IIRC. The Js seemed to make more gains with exhaust and Mugen CAI than the Mugen. I suppose it's not conclusive but I've waited for over a year to decide. I was initially going for Mugen, then Toda, then Amuse and then decided on the J's racing.
