There is not going to be any magic design that makes way more HP that another. Some of you are putting Nameless on too high of a pedestal and are going to be very disappointed when the dyno numbers start showing up on the release versions of the headers.
In fact when I was chatting with Jason on the nameless website I expressed interest in a catted version of their header and he directly told me gains would not be impressive with a catted header and that I want to go with a catless header for good gains.

This is how I see it, but add that removing the cat opens a window that allows tuning that the OEM's couldn't do.
I've been saying removing that heat scorching crap stock manifold cat should be priority one with these cars from day one for both performance and engine health/durability.
Frustrating that a year after buying the car there is no clear header without issues besides the too expensive HKS.
And a 4-2-1 EL may eventually prove worth while for those who want that last +5-10hp at the top end while still fixing the torque dip. Especially if someone is looking at cams down the road.
I just want to fix the torque dip, get the hot manifold cat out of my engine bay and fix the crappy stock tune at this point. But that's looking like over $2k which still too much.
