156 engine nosie/rattle at 2500 revs!??

Hi all, i have a 03 alfa 156, had it for 11 months, full service history 35k on the clock, last service 30k, my car has developed a sound, when the revs hit 2500 it rattles then goes when i go above it?? im the sure the car has been looked after, i always check the oil levels, it does not sound good, it does it when i move and when its just ticking over if i rev up to 2500, has anyone had this or know what it could be, any guidance would be much apreciated projected cost especially!, my brother in law is a ford mechanic but does not know anything about alfas but would be able to translate any technical talk to me!

Thanks in advance

Have a look at the heat shield on the exhaust manifold these sometimes rattle.
