I just mounted a Stebel Nautilus horizontally where the OEM horn was, I didn't even have to make a bracket, just used the same one. The only thing I did was run a rubber hose from the air intake to the back side of the horn. I am going on 2 years with it mounted horizontally even though they say to be within 15 degrees of vertical. I figure for the price, if I can get 3-5 years out of it, I will just bite the bullet and replace it.

Bob,
I be trying to decide which brand and type to get.
Do you have the "full split system" or the "full system"?
And, did you wire in the flashy high beam thingy?
