banshee horn
 

Fuck the 'friendly toot'... I want that motherfucker to blast their doors off from the onset... I hardly use my horn at all... In fact, that Tiller doesn't even have one (not that I ride it anyway)... I could save $70 and just get that airhorn on eBay.

My definition of friendly toot is COMPLETELY different than that guys definition.

I put on a pair of truck horns that make peopel jump for $35, and I actually got the product now instead of some future planned production date
