So, I "bought" this set before as a warehouse deal, but was only sent the trumpets. So I sent them back and reordered this set.Loud is an understatement. Even when placed behind my bumper there is no ignoring me :) The tank fills pretty quickly and holds pressure very well too. Given dimensions, these may be difficult to fit well in many smaller or modern vehicles, but with a bit of tweaking in my much older, larger 4x4 I got the trumpets behind the bumper and the compressor on the wing under the bonnet. Not much airline is supplied, especially if you have to mount the tank far from the trumpets, but airline for aquariums does the job perfectly well.Including all the nuts & bolts for fitting and even a small roll of ptfe tape for the air couplings is a nice touch that helps make installation a breeze
