back pressure is what its called. during the exhaust stroke, an engine will lose power through back pressure. The exhaust valve opens at the beginning of the exhaust stroke, and then the piston pushes the exhaust gases out of the cylinder. If there is any amount of resistance that the piston has to push against to force the exhaust gases out, power is wasted.

go for a 4-2-1 manifold, not a 4-1. 
 
4-2-1 manifold is much better when used with a mantzel. 4-1 you will lose far to much midrange tourqe

i am aware of the difference between a 4-2-1 and a 4-1 manifold 
 
and i dont expect the mantzel to stay on for long
