another glasspack question

yep... another one. but wait! i actually want to make my car quieter not louder!

so i just did speed engineering 1 7/8 longtubes and tsp 200 cell hi flows with my otherwise stock npp exhaust and, surprising no one, the exhaust is louder. however, the hi flows did a lot less than i expected and it is far louder than i expected and was hoping for. i havent even gone on the freeway yet but im sure the drone is going to be... a lot. it sounds great, especially on cold start where the timing is retarded to heat the cats, sounds fantastic even with the stock cam, but volume wise its just too much for me even with the npp forced closed (even with the mufflers closed it is much louder than stock with them open).
i would really like to turn the volume down by a bit without sacrificing the note or causing too much restriction. i was thinking some glasspacks would do the trick since they are supposed to do exactly what i want, eat up some sound without causing restriction. has anyone else with this sort of basic setup went and put on glasspacks? did you like the result? how long were they and where were they placed (under the cabin, right behind the mufflers, etc)? did it help with drone? any better suggestions?
ideally i would like it back to near oem levels, but i would guess that achieving that would defeat any gains made from the tubes and cats via restriction. my realistic goal is to not be that neighbor waking everyone up at 5am/10pm (with the mufflers closed) and be able to have a non yelling conversation in the car on the freeway as well as not go deaf/insane from drone. also not spending a ton of money would be nice too.
