I went to Pepboys and bought the generic, 125dB auto horn for $9.95.
It's the loudest horn out there OTHER THAN the specialty horns, direct change out, no mod's required, and Sounds like an old Olds 88!, and IS MORE THEN ADEQUATE!
If you want anything louder, why settle for anything LESS then an air powered Freight Train horn? (I mean, if you REALLY must be the badest dog on the block)
