Yes, the flow restrictor is incorporated in the size reduction fitting. On
the ones I took apart, the restrictive orifice was 0.070" diameter, but this
was not for your model car, so I don't know that it would be the correct
size for your car. However, you could start with that and see if it cures
the noise without unduly slowing the assist function, then fine tune it from
there.
