The Stainless Bros 18-inch bullet resonator has a 4-inch body with 3.0-inch inlet and outlet connections and a longer 18.0-inch length for increased tone control. Intended for inline exhaust systems, it smooths sound and reduces drone while fitting where space allows a longer resonator body. Use it as a direct replacement or in custom piping that accepts 3.0-inch ports.
