True Dual Exhaust Sound Not Equal
 

Hey everyone, I recently had 2.5” true dual exhaust with Magnaflow 4x9 mufflers (#11366) with no crossover pipe installed on my 05 F-150 5.4. The two sides just down sound the same. The driver side sounds good, but the passenger side sounds like just rushed air. Would this be fixed with a crossover pipe, if so would an x pipe or h pipe be the best? Thanks!
