Dear bro!
actuallt satay walay horn are either chinese or paki, and they are of very low quality, actually theres a coil inside the horn and cheap horn has low quality coil tht go weak day by day, in start they sound very gud, but after sm time u hav to chng them so i'll suggest u to go u bilal ganj, ask for pomp horns imported and install them,and they will cost nt more then 100 Rupees original japan made or any korea/malaysia etc, be sure they are nt repaired, tht last long.
thnx
