What was the idea with removing the resonators? Just trying to change the sound? Feel there are restrictions there? Except for the inability to control the exhaust I think dodge did pretty good with this exhaust.
On the SC GTO I removed the resonator and replaced with an x-pipe and cut out the mufflers replacing with racing "glass packs" (is what it looked like) but they had had a ton of computer time thrown at them and were tuned so that when exhaust flow passed a certain volume the interference patterns caused the exhaust to flow like it was in a straight pipe. Best sounding car I ever had; no rasp, no drone, not too loud unless you were WOT. Better than the hellcat and much better than the GT500 (to my ear).
