Car seems to be more "raspy" than normal?

Hi all

I have noticed the car seems more raspy when accelerating at higher speeds, is this normal? Car has standard exhaust with a Toyo manifold, when accelerating at lower speeds it sounds deeper, just at higher speeds...

Mine is De-resonated and is VERY raspy on the top end (I laav it) and has a deep growl on the low end especially when its in the flat spot range (1500-2000)

I do remember it being raspy standard. But not overly so.
