Why doesn't the Z exhaust note :purrrr: like the G37

If you want to hear the exhaust, put something near the back side of your car. For whatever reason, when my bicycle is on the back of the car. The exhaust would just change note and turn super noisy, it would start to drone. At first I thought my exhaust was loose, turns out either the bike carrier or the bicycle itself is changing the exhaust and its frequency. It's the weirdest thing given the 5-6" gap at the exhaust tip

Why is that weird? 5-6 inches is nothing.

my dad has a G37 and I notice a difference. I have no idea what causes it, but his actually muffler is longer than mine... IDK if that has any effect just throwing that out there
