i always thought the horn was a tad wimpy in the crossfire. i added these two metal hella horns...for a bolder presence when needed. they are double the size of the stock plastic horns and mount to the original factory brackets using the existing wiring behind the upper grill.

it is more of a very loud "mercedes benz" sounding horn.
