I was in the same boat... except I still had the AR HF cats... At that time, I added a small Magnaflow Center X Muffler in the tunnel... made the car sound 100% better. Much deeper tone, still sounds wicked at WOT, no drone.
Since then, gutted my cats as they were failing, not in love with the noise level and tone, so I ordered the 4.5" GESI cats to quiet things down. Not trying to attract that kind of attention.
Hope this helps.
