Drone, Drone, Drone! I know. This has got to be terrible for perfomance. The engine is fighting itself to move the exhaust gasses out. The Crios mod will give some rumble at idle and low rmps but after that the flow will just over take itself and run its natural coarse. I think PSE may be the way to go. PSE routes exhaust directly out the tips from the motor with no BS in the way.
