Louder than you think

I wish that the videos of hella horns did them justice. They are so much louder than you think they will be. Sitting in the car they're not that loud, but once you stand in front of it and someone else hits the horn it's ridiculous. Just how I want it. Now they MOVE over.

You better have a vice!

"Let's torque this 1/2 nut to 400 ft lbs for no reason!" Seriously if you don't have a vice readily available, don't buy this. Grimmspeed should honestly consider leaving the bracket off the back of the horn itself, so that the user can put it on if its needed. I bought the "brotie" and it took me longer to actually remove the stock brackets than it did to install the product. Had to go to my work to use the vice there. So ridiculously tight for 0 reason whatsoever. NOTE FROM GRIMMSPEED: Sorry that the brackets gave you trouble! As this is not a GrimmSpeed product, we don't open or modify the contents of the package. Thanks for the feedback, though!
