A midpipe is an extension of the header collector.
Collector length has everything to do with torque - especially at low revs.
A shorter collector length favors higher rpm.
As long as the collector has the required length for where you want power to peak, the system with the least restriction should make best power.
Most of the 3-1-2 systems have very long collector lengths.
Some of the 3-1 systems have very short collector lengths, while others have very long ones.
On the Daytona, Triumph and the aftermarket used 3-1 systems with either high mount (long midpipe) or low mount (short midpipe). The low mount systems tended to make higher power.
