Where’s the train

I’ve had these installed about 6 months now and let me tell you they are Fn loud. They sound exactly like a true train horn, I know I live where the trains go by several times a day blowing their horn. Friends stand next to my truck hearing them for the first time, knowing it’s going to blow, they jump everytime with amazement to the loudness. Incredible and lots of fun. Love hitting the horn going by someone not paying attention, or when a dog is taking a dump, funny as ****.

HornBlasters The Riot 544K Nightmare Edition Train Horn Kit Review

The Train is Coming!

I’m having the time of my life! Being a bad boy at times… But Hey! You only live once!


Love it

Love this train horn definetly doesn get old waking up people in the middle of the night. For keeping me up with their loud rap music



Never had any customer service issues. So I can't comment there. They were bought by my wife as a gift. Shipping only took 3 days. Took me a month to install. (Work etc) Had to modify install, as I had no place under the truck. Decided to install the compressor and tank in my tool box. And dismantled the triple trumpets so I could mount them behind my grill for full effect. Let's just say. I am way more than pleased with these horns. Wouldn't hesitate to buy again.
