Is it better than the Air Horns?

<img src=http://catalog.com/susq/hella/images/85115.jpg>

How loud is 118 db?

It's made for the highway and it's mad expensive. ~$80 compare to ~$30 for the air horns.

what's the pitch compared 2 the trumpets?

I like the 3 trumpet horn kit b/c it's a little deeper ... r these closer to the 2 trumpet? or the stock horns in terms of pitch?

r they mad loud? worth the $80?
