I WOULD APPRECIATE AN EXPLANATION AS TO WHY A 4 INTO 1 WILL ALLOW THE ZX14 TO MAKE MORE HORSEPOWER AND TORQUE THAN A 4 INTO 2. THANKS

Properly designed, a 4 into 1 will give better scavenging of the cylinder. Read from the link below for a description.

First KILL THE CAPS. Second. A 4 into 1 system work more efficiently by the scavenging (meaning sucking) of the exhaust out of the tubes. As the full one pushing its load of exhaust out it in turn pulls any remain gases out of the other three there by creating a partial vacuum. Then as the next exhaust valve opens and hot gasses are being pushed out by the piston on the exhaust stroke of the motor, they are also being pulled out by the partial vacuum. 4 into2 systems do not have the same effect.

Now when he realizes that dragsters have just short zoomies he will be totally confused.......
but they hit it on the head - it is about creating and maintaining flow out.
