buzzing at 2.25k revs

[Matt606]

when i seem to hit around the 2.25k rev range i seem to have a almost buzzing noise coming from i believe the front end of the car. im not sure what is causing this, i have checked the engine bay but not the underside(possibly exhaust mounts?), this is driving me crazy so does anyone have any idea what it could be?

In my last car, megane coupe, it did it at about 4k revs. Was a really loud vibrating kind of noise.

Just turned out to be a heat shield between the exhaust and the car.
