Sorry for the delay on getting the videos. I have been very busy. But anyway, here they are. Critique of my modified horns please 
Nice! I love the sound, manual valve would sound great with them.
Please slap the guy holding the camera a couple good ones. Whew, made me dizzy trying to watch it.
^ Hey thanks, and yes I will slap him!
Cool vids and youâve got a great stretch of road there! I wanna hear you dump the tank tho! Yeah itâs hard to keep a camera steady without a tripod, and zoomed out only amplifies the shake. But all in all, the horn sounds great! And glad you flashed your lights in the first one, itâs interesting to hear how much a delay there is when far away. Thanks for sharing!
^ Thanks! Both of those videos are pretty well ran out of air. 7 gallons is not quite enough volume for a modified k5, but I still love it. I hardly ever hit the horns long enough that I need more tank volume, so it works for me. It would be nice to have for a neater video though.
Ah ok gotcha
Hey Iâll have to watch your vids tomorrow on a highspeed connection.
But I âriggedâ my K5 just for the weekend with the 5/8" ID and about 8 gallons. It drains pretty quick! And my bells are unmodified.
^ Ya, air goes fast, but they are louder than hell!
They sound really nice. Seems like the high manifold makes the 4a and 5 a little louder and the whole chord sounds a little âbrighterâ. I like it.
^ That may be caused by the 6mm inlet orifice mod⌠I love it!
