    What kinda mods? what type of exhaust are you running? Are you talkin about 1/4 time improvment?
    open headers will take away a lil bit of lowend torque, if you have an aftermarket catback then i wouldnt worry about running open headers.

    Open headers is annoying. My cammed car felt terrible across the powerband when I was open headers. I know it lost power down low, not sure what happened up top.
    How are you taking the exhaust down when you race??
    Or do you have cutouts??
