Was wondering which replacement performance muffler would best suit my needs. Have the hemi with Big Horn package(dualexhaust) . Considering Flowmaster or Magnaflow. Here is my concern, want a little more bark at idle and on acceleration , but DO NOT want that teeth rattling ressonance when cruising on the highway. Little cautious about 50 series Flowmaster, maybe 70 series would be better or which Magnaflow might work. Had a Gibson dual set up on my F-150 and it was perfect, but they don't make much or anything for the Ram. Any reccomendations would be great. Thanks.
