today is your lucky day, a video of what one sounds like!

its basically my K3ha and the K5’s tied into the manifold via a “T-Fitting” I had sitting around " which I have lots of them lol" Now, to find a way to cram the K5’s onto the Honda along with the K3’s… 
Wow indeed. You had to be there I guess to feel the impact of that
I was expecting it to sound like poop, but it’s actually not too bad. Suppose it’s just doubling up on 3 of the bells without adding other frequencies.
LOVE the sound! I’m thinking of getting more remote mounting brackets and cutting some holes in the spare tire well.
Please if you have the time explain in detail as I’m a long time lover of these but finally put a budget together to make the horn I want for my excursion. Or if you have PayPal. I will gladly pay for your help. I listen to horns and this seems even louder then the k6lla from a company I’m sure it familiar with.

If I read correctly you have 2 other horns on top of that connected?

What would it rough estimate cost to build your setup.
