Anyone knows what db does the stock horn for a 2005 S4R has? I couldn't find this info in the manual or forums.
Also, it seems that the loudest choice is the Stebel Nautilus... but it is bulky and needs a relay. Anyone has a picture of this horn installed on a monster?
If you have a better choice that is louder than the stocker and doesn't need a relay, please let me know. 
Thank you guys!!

I currently have a 130dB "Low Tone" horn from the auto parts store mounted in the stock location. No more "meep meep" from my bike!

Stebel is supposed to be loud ~

I have the Rivco electric horn set. Both low and high note are installed in the stock position, no relay needed.
They are loud like an aggressive car horn, scares the ones I need to scare.

Mine is S2R - don't know if stock position is the same as S4R?

I have the Stebel Nautilus, one of the best mods I've ever done!  It IS BIG though, so finding a spot might be difficult depending on your bike.  But living in NYC, it's was definitely worth the hassle of installing it! 
Taxis part like the Red Sea to Moses, at just one short honk of this horn.    Sounds like a truck

mish, i can't believe what you guys have done with that 620, that is SIIIICK   

i think the taxis part because they see that horned gas mask in their rear view and think Satan's after them   

i too would love a very loud horn. would some of you please post some pix?
and where did you purchase?

THanks for the feedback! Anyone Knows the DB on the stock horn? So I can compare to the one I will end up choosing THX

Don't trust db information, I've seen them measured at 4" - of course they will be loud at that distance. Others, like ambulances are measured from several hundred feet.

Stock:   meep meep
Rivco:   like a large car
Stebel: truck

Someone on TOB had a thread about a set of Hella horns they put on their bike.  They were 4 or 5" in diameter, and he mounted them under the fork.  The sound file scared the shit out of me, it was pretty intense.

I spend a lot of time on some Dual-Sport/Adventure Touring sites and Stebels don't really stand up well to MC use, in that application.

IMO, still the best.  It's my next mod, now that I've shitcanned the airbox and have room for them.  (I'll mount one in the OEM position, and the other on the front left mount for the airbox, along with the relays.)

These are all measured at 4''

Rivco= 118db
Fiamm Freeway Blaster Horn= 132dB (Really cheap)
Stebel HF 80 Series   = 133dB (looks like the rivco and Hella)
Stebel TM80 magnum = 136dB
Stebel Nautilus = 139db (loudest but bulkier)

Hope this helps.. I may go with the HF 80 Series since it looks like it will be the easiest to install and has good output. I you find the Rivco loud.. then the HF, according to dbs, will be a LOT louder. Hope this helps!

I also have the Stebel Nautalis and it is LOUD.  It's so loud that when I use it I shit my own pants! 
I mounted mine on the same mount that the OEM horn was on.  I just had to remove that flat piece of metal between the forks that sits in front of the horn.  I also used a couple of strips of metal that came with the Stebel used to offset the horn to allow it to fit.  I didn't use a relay and it works great.  I'll see when I can post some photos.

I just installed the Fiamm Freeway Blaster in the stock postion with no reley and it is loud.

Did it myself too 

yeah, i put dual Nautilus horns on my car (replacing the hi/lo crap horns)

it was fun in new york city honking at jaywalkers.. people literally jumped and shit themselves..
