Peace, mercy, and blessings of God be upon you. I have an RBK electronic muffler, 3-inch inlet/outlet, stainless steel. Clean use, less than 9 months old, with two remotes, the device, and the wiring harness. The muffler is sound, free of clogging and damage. It was installed by Abu Khalifa. The muffler is for sale, reasonably priced, and open to offers.
