Hi! last week I installed a new 5zigen(the new version FB-JXE10 70 mm pipe diameter) it sounds deep and throaty but I noticea drone iat 3k. I search in the forum and found that the Drager II doesn't drone to much. What is the diameter of the Drager II? Does the pipe diameter and the canister size have an effect on the drone? I like the sound of my 5zigen but the drone at 3k is still to present. Does the Drager II drone at 3k? Anyone that had heard both of them the new 70mm 5zigen and the Drager II can tell me wich one drone less? If the Darger II drones less I would sell my 5zigen and get a new Drager!! Thanks!!
