    Well the vibration is definitely from the O2 sensor resting on those two lines as it doesn't vibrate when I put it in reverse which lifts the O2 sensor up and away from those lines. So what am I supposed to do about this? Here's a pic.

    That looks like power steering lines...

    If so, do whatever you have to do to keep the O2 sensor off them. Power steering fluid is flammable and the O2 sensor gets VERY hot.

    Hmm well I guess I'll try and put my shortened dogbones on and see if that rocks the engine forward enough to allow the O2 sensor to not hit those lines. I still don't get why my car is the only one to have this problem with S&S headers .

    Ok a problem I foresee with using the shorter dogbones is the front header conflicting with the fan shroud. Would it be a problem if the header melts it a little bit?
