SoC, The wave isn't influenced by resistance, but by expanding , the velocity drops do to entering a muffler (an enlargement) or atmosphere and is turned into pressure , it then reverses as a negative pressure wave and moves back up the header. the muffler kills noise ,if it has a baffle this will slow the gases and provide some back pressure on the motor ,this helps flatten the torque curve ,making it less peaky. A straight pipe , with or without baffle, will not allow the pressure wave to expand until it reaches the end of the pipe,which makes it bad for wave tuning, and you'll make less Hp .I'm not up on the voodoo muffler but if it's larger than the header pipe I'd go with it or any muffler before a straight pipe.
