Well, I guess I've been unlucky then because every time I am in the drive-thru with a diseasel in front or behind me, the nice lady in the box cannot hear a word I say and I cannot hear a word she says unless the guy in the truck shuts off his engine... which is what he has to do to place his order when it is his turn to talk to the nice lady in the box.
There is a video somewhere here on 'Mud where a guy was all giddy about his new-to-him 4BT conversion and he was saying how you could carry on a normal conversation with the hood up. Then he takes this video to "prove" how quiet the damn thing was. I watched the video and you couldn't hear thunder while that thing was klanking and banging and clattering. If that is quiet then someone needs to have their ears checked. I'll find the video for you if you don't believe me.
And they smell to high heaven.... all of them. phew.
