Guys, a resonator will not control volume (and it WILL be loud) it's there to handle resonate frequencies, basically rasp. Go on youtube and look for videos before and after for resonators.

The stock stuff flows poorly - the Stock Y pipe (in the resonator) is crap, the stock muffler is quiet and crap.

Replace them both and try to go with a quieter option, something like the Vibrant Ultraquiet resonator (which has some muffling capabilities, but is NOT a muffler replacement) and Dynomax Superturbo Muffler (which won't flow as well as something like Borla XS, but it will be quieter), or something else of the like. Use a large chamber if you can fit it, as it will hand the volume better.
