I really wish someone would try out a stepped, equal-length, long-tube, 4-1 header for this car.
Thanks again for sharing. I'm looking forward to seeing how this data compares to Motorsport24's headers.

Word.
I suspect the reason the tri-Y headers didn't work is due to the uneven pulses of the 90 degree crank. Try-Y works well on typical 4 cylinders with even firing pulses. It's my understanding that 4 into 1 still makes more top end power when tuned well, even on a four cylinder.
