Review on 🚂 MPC M1 3-Trumpet Train Air Horn Kit with 110 psi Air System, 150dB+ Sound Level, Made with Metal by Nick Gathings

available That makes it so much fun Installation was a little tricky since I put this on a 2015 Denali HD pickup It was new so I was worried about fairings peeling off and such It's quite noisy and very unexpected I use this for the dumb ones People getting in my lane while texting and driving Works great for that! Scares you know what about them. I've had it for 3 years without a single problem. I installed the supercharger unit under the back seat. It's pretty quiet. The Air hose is pretty cheap but it lasts 3 years so it's up to you to decide if it's cheap.
