I got mine from Sound Innovators in Florida. It came to about $300 including shipping.

The largest trumpet is about 19" long. Not sure the diameter but its pretty big. You can see in the pic that its bigger than the alternator.

BTW, a 1/2 gallon tank is not nearly enough. You need 2gal minimum.

Dennis - I doubt I'll make MOAB this year. Keep me in the loop though, I really want to go out there!

Sheez Taz, I might have to pass on these. I don't know where I can mount them if they are 17 1/2 feet long.

Sorry Buddy I think I was getting a little sleepy. I'm going to do more detail measurements myself today. Taking digital camera so I can post those pics as well. I have to go to the shop and pick My girl up for a weekend of driving to test out the new supercharger and try to burn one tank of gas up as fast as I can and maybe get it out of My system. I may get tossed for street racing so I hope I can have My daughter call one of You guys to come and bail Me out. I'll pay You back immediately. They have never had anything to do with the law and would be scared to death. I told them just leave Me in there I'll do My time. It was funny to them at first untill they saw I wasn't laughing and then they got scared that I meant it. I told them never been in a jail may be one of the last unique experiences I will ever get to have. Nice thing is I know the Judge and the Chief so I probably would not get left in there even if I wanted to.
Seriously I will have more detailed numbers when I get back late today. have Pics also.

Oh, you're being left in there alright.

It's a little over a tank full to get down here. I'll really test it for ya.

I'm getting a little more info on the horns a little at a time. The horns are being changed out because a few are old but, because most are to loud. No joke I talked to the guy who works for the RR and He said the horns the newer horns are to loud for some of the city ordnances that they pass threw. I'm going to attempt to place a Pic The ones I show are mine and You will be able to see where We have started polishing the right horn. It looks like they will polish up nice along with some minor smoothing of some seams. I placed them on the checkered flooring to give You a shot of the size of them. They do wieght 20 lbs.

Nice! Looks pretty heavy duty. Are those Grover?

I believe those will mount nicely in the void just above the skid plate and below/behind the radiator.

No need for mine to be polished.

Looks like there is a regular old airhose fitting on the manifold.

Ken You are right. It is a regular air hose hookup. We have been playing with it. The horns do not come with any valving. But, What We have been doing is hooking them up on regular air hose but, You could run stainless or copper if it was near heat. I'm waiting on the guy to tell Me what they can be bought for. I know what I have to pay but, I told Him if My Buddies and I want them I expect a better price with volume.
It would help if I knew how many to tell Him We estimate. There is a chance that there is a limited number so once I get details I'll just go through the thread and see who asked first and work down.

Dan I did not look at name brand. But, they are extremely heavy duty. It would take quite a hit to break them.

Ken did You get My email?

Actually, they look more like Nathans. K3LA's maybe.

I ordered a better compressor & tank today. I'll keep you all posted as to how they do.

I think so too.

Taz, yes, just hard pressed ot look at it. I will, you know that. And thanks, I did skim it in between boxes.

Here is a pic of the one my friend has. It looks like only one part of the whole assembly, or else it's just a really old one. Like I said, he found it at the junk yard. This would fit under the hood no problem.

I'm getting this one installed in time for Moab.

It's about a gajillion times louder than Dans.

Looks more like a porno-graph than a horn!

I still have the 5 gallon stainless steel tank and the compressor and air lines I am going to mount. I wonder how long I could lay on the horn with 5 gallons of air.

Guys, Count me in for one of these if there are enough available please!

Dennis, do you run that baby on Vacuum?

Why, do you think it'll help?

You Guys have got to see this bad boy.
