Spare tire Delete
I was blown away on how loud this setup was after it was installed. Soon I will be adding two more horns to complete this kit.

Great set up
Bought this set for my 2015 Toyota Tacoma. The dual tank set up is just the perfect amount of air. Liked that I did not have to take away from my bed space and they are tucked about nice and look great. We did not personally do the install but my truck was ready to be picked up after about 2 hours.
Great experience with horn blaster
Great products and pretty straight forward to install only tip for the people at horn blasters would be to make the instructions a bit easier to understand . Overall no complaints other than the instructions.
