2 prototypes in hand, plan to do some dyno testing vs OEM and PLM headers in the next 2 weeks.

Is the left hand one a 4-1 or is the picture playing with my eyes? If it picks up power over the plm I'm intrested.
Both are the same design. We passed on 4-1 as it was very peaky and overall torque was about the same as it lost as much as it gained. We worked with a great K series header manufacture and another header designer with mathematical modeling. They came up with the same parameters but what works in theory or tested well on the Kseries doesnt work on the S2000.
The new design is a simple 4-2-1 with a little secret sauce we noticed from Honda.
