FDR Electronic Muffler, got it from Al-Hajri, used for 6 months. It was on a Hilux and fits most cars with welding and fitting. Its sound is high-pitched and pleasant, not annoying. If you close it, it becomes stock. Its sound is in the ad, and it has two keys. It needs a valve for 60, which can be done at Al-Hajri himself in the old industrial area. Also, I have a "Rocket" muffler, its sound is very loud. Best offer.
