Author: Dennis J I added these to my 03 VTX-1800 Retro. I'm not much of a technical person, but installation was moderately easy for me.
These things ROCK!!! One quick tap of the horn button and those things belt out a sound that sends people scattering. These are an amazing addition to my bike and are a superb safety feature because YOU WILL GET NOTICED!
In my opinion, these are way better than a set of loud pipes!
