Complete exhaust replacement, V&H power duals with Rush 3.5"s and 1.75" baffles, SE AC, SESPT with dyno by the dealer. It will pop when shifting gears and if I let off and RPMs drop below 2K. Was able to watch the dyno runs, it popped then, tuner said it was just the nature of the beast. I did retorque the flange nuts, all were loose when I got home from the dealer.
