Re: Which exhaust to go with?
IMO Flowmasters with turndowns before the rear axle is the worst combination for drone. Everyone has different sensitivities and tastes but the chambered muffler along with the sound wave bouncing between the pavement and truck bed can drive you crazy and give you a headache sometimes. While they all drone at certain rpm's -any- other muffler internal design with tailpipe(s) going to the bodyside or rear will help a lot. Some have even added small glass packs to the tailpipe as a resonator and then there are quarter wave tubes you can install in the tailpipe to cancel out sound waves as well. In my daily driver I do not have any mufflers at all in my full length system but I do have a quarter wave tube tuned to length and have no drone at all but a healthy sound.
