really dumb ? regarding horns

so i been doin some research on satoshi grilles and grillecraft and what not. i noticed something in all the threads i'm looking at. on the upper models (i have a base reg. cab so anything above that haha) i'm seeing two horns. do the sr5 trucks on up have dual tone horns? im curious because i absolutley hate the single horn on my base model. it sounds like a pissed off trombone or something...

 

I have a TRD OR.. I think I have two... will check when I go to the truck to go to work and let you know...

 

I have a TRD Sport, and I have two. Take the plastic thing off the end where the sound is supposed to be projected out and it makes it a little louder.

 

well its not so much the loudness, i just prefer the sound of the dual tone horn. i might try to find them in a junk yard and wire in the second toned horn.

 

Got me on the thread title.....thought it was gonna be about these horns, lol................

 

I have two horns , but I think they sound like shit. I want louder! I put a 139 db horn on my bike, and am looking into doing the same for the truck.

 

I'm thinking the train horn would be a good fit
