I wouldn't rule out injectors, but if it's running good, it's not likely the source.
It does gets faster with the rpms, not sure if louder just faster. Can't really hear it when in the higher revs do to the downpipes. Sounds louder on the passenger side up by the turbo's. Trying to rule out every possible cause before I drop the cash on new rods.
