Will changing timing effect tune

I finally got a decent vid of the sound that I was trying to explain. Alot easier than using words to describe a sound.
I took the vid in the morning because thats when its most noticeable but even after the car is warmed up you can still hear it abit, but the exhaust covers it up.
