Upgrading a LOUDER horn for Yaris

[xtremesniper]

I think the hella supertones are the same dinky sound, just louder. Kind of pointless imo. I'd go with something like a Tundra horn or something from a Lexus. Deeper and actually more "horn" like.

I'm having my dealer look if they have any spare horns laying around they can toss my way. The only problem is that to get to the horn on a Yaris, you have to take the bumper off... Or at least that's what it looks like from first glance. Correct me if I'm off base.
