[Bad Gas]

jimdejet, i have used many diifferent aftermarket mufflers, including Gibson. I got rid of the 2k drone by cutting the tailpipe off, so that the exhaust system dumps just past the axle. Exaust flow is directed down, no longer out the pass side of the truck. It seems the factory tailpipe resonance contributes to drone. Now, this should not be done on an SUV, due to the possibility of introducing CO into passenger compartment, big no no. Also any moisture in exhaust will accelerate rust, (see f150 pass wheel corrosion issues). Also you'll dump your exhaust on your trailer. Give and take.
