Default Magnaflow Resonance- Help!

Help! I installed 18" 4x9x18 Magnaflows on my 96 SS. Although I like the exterior sound, I am getting terrible interior resonance at 1800-2100 rpm. Is this normal? Is getting a Magnaflow dual (to be used as a resonator) the best option to fix this problem?

If you angle the pipes down it helps out. Sorry for not being very much help

If you don't have an H pipe, add one. It will make a world of difference and can e done at most muffler shops at a reasonable cost.
