Sometimes. But, sometimes resonators are used to create constructive intereference and can improve torque at certain rev ranges. So removing them may induce a torque dip at some RPM. This is the case in the NA miata, where the resonator has nothing to do with sound, but increases performance.

Sometimes, though, the torque dip is caused by the intake tract itself, so removing the intake tract entirely gets rid of the torque dip too.

Anyway, it sounds like the solstice intake is pretty bad anyway (engine in vacuum at WOT according to one poster), so an open CAI sounds like a nice idea.
