Here's what i got just because i wanted something louder. Direct stock replacement. Comes with 2 horns, I just use 1 of them. Much louder and normal sounding (not hollow and weak). If you need, I can record a clip and attach the sound (neighbors might not be too happy). Here's a link for you to see them:
