They tried various intakes and exhausts on engine masters and found out that what is best in all cases is the freest flowing. The best intake was a salad bowl. The best exhaust was a straight pipe. The best-sounding exhaust is the X pipe with good mufflers to kill drone. I can't recommend that you watch Engine Masters highly enough, even though I sometimes wish they'd do another test or two in an episode. The cross pipe is important for scavenging, but the muffler can only kill power, never add it.
