In this months jap mag, Phil tried out some aftermarket headers on his ra. They actually made the car lose power and a lot of torque. Did anyone notice how much smaller the ports were on the new headers compared to the oe set?? Could have predicted the results before he swapped them! Seemed a strange decision to make considering how well regarded a good set of ported oe headers are.
