Stock cars aren't usually optimized for pulse tuning alone as there are so many considerations that compromise design. For emissions purposes, some exhaust is reburned with the fresh intake charge, which exhaust overlap would allow and back pressure would assist, if that's designed by intention on the pipe side.
