    This is for seventyK5. he is looking at the Baffles that I believe Summit sells that go onto the collector of a header. It says these will help with sound, but the question is will they create enough backpressure to keep from damaging the motor.

    As long as you have some kind of header or exhaust manifold you cant damage the motor or valves.
    Lack of Back pressure has absoultly nothing to do with motor damage.
    Excessive back pressure can cause damage.

    Cool ok he was told something about when the air is very cold with no or very little exhaust cold air getting sucked back into the hot valves and damaging the motor /forums/images/graemlins/dunno.gif Not sure just want to make sure. This will only be temporary about a month until he can pay to get the rest done. /forums/images/graemlins/waytogo.gif

    The only time you really have to worry about that is if you are running No exhaust manifold or a very short head pipe. Running without a manifold will warp the valves. Because of the extreene temp difference.

    He should be fine with headers they are plenty long enough.
