Exhaust note changed almost sounds like misfire

So I recently took a pretty long road trip, 800mi round trip. During this trip I noticed the exhaust note starting to sound different when I WOT. It sounds almost like it's beginning to misfire but isn't. The exhaust pulses seem alot closer together almost like it's pushing a lot more exhaust gases out. This is also accompanied with increased vibration. Performance doesn't seem to be affected and I'm still hitting target boost. Mods are dci, jb4 map 1, 7in I/C, cp, tial bov and PE exhaust. The car has about 36000 miles on it and spark plugs have about 3000mi on them. Should I be worried? Any idea what it could be? Thanks
