Growling noise at higher RPM

[Gee_35]

I just bought a G35 coupe 2 months ago and from day one i have had a growling noise coming from the engine only when i push in the clutch at about 4200rpm or higher. ( i get the noise in every gear shift 1st - 6th if i'm in higher rpm). i do not get the noise until that rpm or higher. there are no vibrations anywhere or anything felt in the shifter. the car has 20,000miles on it. what do you think this could be?? thanks

I have only test drive experience with this car, but I bet it is your clutch or transmission. I think the synchronizers can be a problem.

I bet there are posts in the Z33 forum about that.
