Bring the BOOM!!!
Install was a bit more challenging due to the size of the 5 gal tank. Overall it's a lot to blast this horn and people love it when you give a short burst. I had an idiot riding my tail yesterday so I gave him a 7-second blast. The look on his face and reaction was simply priceless and well worth the cost of admission!!! Love, love, love my Conductor's special 540

Super Loud!!! Easy install!
Love the tone of this system! Installed by myself in a few hours. Purchased the spare tire delete bracket for a discrete clean install for the horns. Installed the tank and compressor in the cab for a prolonged life of the system. Well worth the money! You generally get what you pay for but in this case you get more!
