Yup, got rid of that wimpy horn and installed the Hella Supertone Twin Horn Kit using fizyliftingdrnks install guide in the DIY/How to thread.

Took a couple of hours, only because I had to return to Lowes to get some connectors, which I thought I had plenty of.

A lot louder than stock, but I'll try it out more tomorrow morning on my way to work. :grin2:
