I have a '7 Forester Sports XT 2.5 Turbo(it has a different front bumper, grill, etc. than the XT). It's horn sounds o.k. compared to our FJ Cruiser(anemic single horn, it could definitely use an upgrade) and our Xterra. Are the Hella Supertones really that much louder? Has anyone with a Sports XT installed the Hellas for a direct comparison? Thanks for the feedback.

one pair of supertones should be loud enough

Yes the supertones are a huge improvement from stock. Here's some of the pictures I took when I installed the ones on our 07 FXT sport. http://www.subaruforester.org/vbulletin/178657-post38.html

Stealth mini airhorn is another option. About as loud as hellas but richer tone.
