  It is kinda hard to hear the knocking with all the other noise assoicated
  with our Spit, but the engine does knock.  I always thought the knocking
  noise I was hearing during acceleration was my exhaust pipe hitting the
  frame.  But when a friend hear it, he say it was coming from the engine
  compartment and is not my header hitting one of the A-Arm bolt. 

  If you are just reving the engine you will not hear the knocking it 
  has to be under load while you are accelerating.
