  1. X-Force equal length headers?

    N/A Tuning
    Hey, I have a 2004 Subaru Impreza RS and am looking into getting equal length headers. I've been researching and seen the power and torque gains from the OBX and MRT headers but haven't been able to find anything on the X-force 4-2-1 headers. Has anyone run these headers? How would they compare...
