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.
