Noise changes past 70k miles?

I have a little over 72,000 miles on my M3 and lately I've started to notice that it sounds a little different at past 4k rpms. It went from a deep sound to a higher pitch sound almost italian like. Is this something I should worry about? Is my engine going to blow up? *knocks on wood* Car drives just fine, no other weird noises. Almost as if I just changed the muffler.

Also I have the OEM perf pipes mod. No engine mods and stock airbox, cats, and resonators.
