I considered a full blown cat back. I had an x pipe Zoomers on my last SRT and loved the sound.
On my HC, I decided to experiment, based on feedback I read on other forums. The Vibrant 1794 12" stainless glass packs were only $50 each and just what the doctor ordered.
After about a month of driving, they really settled in, with a great low rumble, at idle, a mild growl at cruise and an insane roar at wot.
No drone, at all.
I replaced my mufflers, with the 1794's and left the resonators, at the tips.
Pretty amazing...
