I have added a Thrush glasspack where the Festiva resonator went. It does seem to me to noticeably cut down on cabin NVH, especially at freeway speeds. I wish I had known to put one on my ATX, which needs it more than my 5 speeds!
I always get the smallest one with 2" ends (it's a bit larger than the stock resonator):
I obviously recommend it.
