Curious to know the performance differences between the Hertz ST25 and ST35 horns. I have a store credit and can get either model. Not sure which one is better for my fairing location. Rushmore batwing. If i go this route, i guess i would mount them where the stock mirrors are on a SG. Couldn't find comparison.
They would be used on their own channel with my JL600/6.

Now that I have my hogtune lowers installed with PRV250s in my wethead lowers and I already have a set of PRV 500s sitting here staring at me... considering my next system change.

 

be careful about your mounting,,,the only horns that i've seen that go where you are talking about without more mods are the DD's VO B3. the ST25's are just a tad longer/deeper and might need some mod work to work. put your prv's in up top, you'll be glad you did.
