    hey guys
    when i first bought my gen 4 it had an 3sge exhaust manifold on it
    everytime tvis would open it would sound like vtec/lift

    i then changed the manifold to the correct one and a full exhaust system as well as a pod filter.
    ever since then i havent heard intake noise
    ive cleaned and sandblasted manifold, overhauled the flaps
    replaced every vacuum line.

    i checked the loom and found that it was giving 0.3V when the ignition is on, them read that i should be getting 12v, the other vsv valve plug was getting the 12v so i swapped them over.

    after all this it still hasn't changed

    is this normal or am i doing something wrong ?
