What is problem if my car makes noises like a motorcycle

Have the catalytic converter checked for broken catalyst inside. Have the drive belt removed to see if the "whinning noise" stops, if it does, check driven componets for that noise by turning each componet by hand while listening and feeling for a problem. Mechanic may be needed OR a car savvy buddy, i do not/can not know if you can do these things! Respectfully, pushrod.
