Since V8's fire unevenly, exhaust exits in pulses rather than a steady flow. While one pipe is filled with pressure the other pipe is relatively pressureless but the connecting of the two pipes in a siamese pattern allows pressure to be released to the other side. This action allows the exhaust to pass through the pipe quicker and this better "breathing" increases horsepower.
