Swap horn for Toyota/Lexus
 

I think this car deserves a much more mature and elegant horn based off of its looks. I plan to go junk yard picking for other horns. I've seen a few videos on swaps for louder horns but nothing fancy.

Do you guys think Toyota and Lexus horns would be plug and play? Same wiring etc.

Just get hella horns for 30$

Might not be plug and play, but if you can swap the plug (if needed), then it'll work fine.

Other Subaru horns may be.

Hella horns aren't plug in play. Not the ones I bought, but it took me 5m to figure it out and there are videos online that give enough guidance to figure it out if you're the technical type. Pm if you go that route and need help.

Thanks. I assume it's just cut and crimp.

Find some 80’s Cadillac horns.
Those sound like a bloody locomotive at a level crossing.

I've gone through two different horn setups on my BRZ. The first was the Cadillac 4-Note setup, which sounded lovely:

That wasn't quite loud enough for me, though, so I eventually went insane, and upgraded to my current setup, which is probably a little bit overkill for most folks.

PNP possible but not probable?
Back in 2011, I replaced my Yaris' single horn with a pair of IS300 hi/lo horns. I happened to find a "Y" harness adapter kit, with Toyota part numbers, on ebay from Japan. It had Toyota connectors and Toyota horns. Other than removing the bumper cover it was easy-peasy. Sounded great, too.

But I've never seen those parts or the seller since.

I was hoping to do the same with my FRS and contemplated taking the horn kit off of the Yaris, when it got totaled (which led me to buy the FRS). But then i realized the car is built by Subaru. So the connector in the car probably wouldn't be compatible with the connectors on the horns.

So, basically you'll have to buy two Toyota horn plugs and make your own "Y" harness. Then you need to buy the horns. Of course, you can just snip the connectors from a junkyard car when you get the horns but then it's not PNP anymore...

You can go to a junkyard and look for larger cars. But if you want something that will make your car sound extraordinary, find horns from the 80’s Cadillac or Buick. They usually produced four notes instead of two like most cars do nowadays. The notes are usually A, C, D, and E. They are printed on each horn. The wiring shouldn’t be a problem as there’s only one wire coming out of all GM horns. These are some of the loudest car horns you can find.

I have the JDM Subaru aftermarket horns for Forester, they are almost plug'n play. You have just to rotate the bracket on one and the plastic on the other.
