My car also got whistling sound. The sound come from exhaust. The whistling sound only have when I stepped the gas pedal when the car just started. I dunno what wrong too.

 

[kelvio]

this sound might due to the inproper welding of the exhause
bring it to the mech and check and weld it back,
or check ur self, just jack up and use soap water to check for leaks
