Yes an h- or x-pipe can settle out some of the noise. I prefer an h-pipe, but a lot of Buick guys swear by x-pipes. The connection reduces some of the pressure from the pulses as they are scavenged back and forth. The other reason is that it effectively doubles the frequency of the exhaust note, and the higher frequencies aren't as annoying as they have less energy.
