I have dual w/ 2 #11225s. Yes sounds like Ryan said, but if you hear my truck go by it has this kind of "muffeled cough" sound. Not good & don't know why is sounds like this?
Do you have an x-pipe to balance the exhuast pulses? Also what size piping did you use? If the piping is too big for the flow, it will be turbulent and not efficient (potential loss in performance and degradation in sound).
