i have recently noticed that my engine pitch changes to a higher raspy-ish kind of sound once i go over 3000rpm's. is this normal and im just hearing it now or does something need to get checked out? my car drives normal and no lights on, just wondering. thks in advanced

when was the last time you changed the oil? From what i've noticed from my civic's adjusting the valve springs helps raspy'ness out, but the IS doesn't have em. Instead they have discs that are a set thickness and anybody help me out here.. the discs don't need to be replaced unless there's something noticeably wrong.
raspiness can sometimes be the exhaust too, just listen from the outside
