New guy from Canada here. I’ve been lurking on the forums for a while and now decided to post and show you my setup and ask a question.
I’ve recently finished installing a set of Wolo Siberian Express horns in my Expedition and I love them!
I didn’t have money for a proper air setup right now, so I’m using a 5gal air tank i got at walmart for $30. It uses a regular tire valve on intake, so i can fill it up from my garage compressor (or the mini compressor I carry around in my truck). An 80 PSI fill-up lasts me about a dozen honks, which means about a week’s worth of honking.
I know this has its drawbacks (no proper drain), and the 5gal tank is also rather big, so I plan to install a proper 3gal air setup in a few months and move it under the truck (the air tank is currently installed in the cargo area for easy fill-up).
I had to remove the spare tire to mount the horns. They’re gigantic!! I couldn’t find any other place to fit them in.
And that’s why I wanted to ask: do you guys know if it’s possible to disconnect these horns from the manifold without damaging them? Or are they glued to the manifold? If I could separate them, I could easily find a way to install them under the truck without having to sacrifice the spare. I didn’t think to check if they can be disassembled before I installed them and I wouldn’t want to take them off just to check.
Here are some pics of my setup and a short vid of how it sounds.
Here’s the Air tank. The 12v plug on the right is what powers the valve.
Thanks for the warm welcome and the tips. Wow, never realized there’s a delay! Would that be caused by too low pressure? I was running 80 PSI which is at the lower end for these horns. Recommended working pressure is 80-140. The tank is rated 100PSI, so I could give it a bit more pressure and see what happens.
I’m a bit pissed I didn’t think to check if i can separate them before i mounted them. I’ll do some more online digging and if I don’t find any info I’ll take em off and take a look. Hope they’re not cemented to the manifold. Otherwise I’ll see if I can move them under the front bumper somewhere.
Thanks guys. I’ll bump it up to 100 and see what happens. Don’t know if I can do much about the air line and fittings at this point unless I change the tank and valve. They’re all 1/4" and i do agree that the air line looks awfully narrow for such big horns.
This is actually my second set of horns. You can see the tiny piece of crap I used to have before in one of the pics I posted above. They were more or less loud, but sounded squeaky as hell.
When I upgraded to the “Siberian Express” horns last month I thought I had finally made it to the big league (the largest of the three horns is about 2 ft long). But now seeing the gear you guys have on this forum, my new horns seem like midgets I’m gonna keep these for a couple years anyway and then maybe upgrade to a K3 or even a T3, if I can afford it (without being sent to sleep on the couch for a few months, lol). In the meantime, I’ll try to get the best out of the Wolos: proper air sistem, larger air lines, probably a new valve.
I actually just posted a question about the same thing you are asking. I am looking into getting these horns and would like to know if they come apart also, so if you do find out let me know please. By the way, how do you like the horns?
Hi Steve. I can confirm that they do come apart. I decided to bite the bullet one day and just dismantle them. It was pretty easy. Just unscrew and remove the valve and bracket and then you can unscrew each horn from the manifold.
I moved the valve inside the truck close to the tank and ran an air line out to the manifold, which i left attached to one of the horns. Then I ran air lines from the other two ports of the manifold to the remaining horns.
All fittings are standard NPT so it was easy to find the parts i needed at the hardware store. I wish I could tell you exactly what to buy but i don’t remember exactly what I used (this was back in August). I should have also taken some pics, but I didn’t.
I love the horns. They’re loud and i managed to scare a few people. They definitely get people’s attention.
Didn’t want to drill holes in the dashboard.
