DISCLAIMER: Train horns are not for everyone. I am sure on this forum like all the other forums, there are going to be people that will hate me for this mod and there are those that are going to love it. I own my retail store, these mods i do to my car, is a tool for me to sell and install product! Do i abuse the power of having loud horns? NO, i dont do the @SSHAT stuff you see on youtube hornblaster videos. I do use it when other drivers feel the need to double park next to a empty parking spot so they can "holla at their man" and i have to drive around them into on coming traffic. I use them when the @SSHAT that is talking on the phone and driving at the same time that isnt paying attention whiel driving.
It only took 3 months for me to resist the urge to install train horns into my latest ride. 2003 toyota 4 runner v8
