Help with my pressure....
 

Please forgive me for the newbie question, I am new to the hemi world.
I have an 06 Mag 5.7 hemi with a cold air intake being the only mod besides 2 18 inch glass packs in place of the stock suitcase muffler..

I like the sound at w.o.t. But the idle and low rpm are a poor showing for a Hemi. So I tried removing the rear resonators, awesome sound but no back pressure :( the drone didn't really bother me but the loss of low end trq and overall response does... So my question is how can I keep that sound without sacrificing as much back pressure as the stock resonators apparently give?? Would adding a j-bend on the ends and smaller diameter help/be enough?
If anyone else has any incite on this back pressure issue without buying a 600 plus cat-back system, I would most appreciate it..
