Powerage slip-on exhaust for the Royal Enfield Himalayan 411, a hand-crafted stainless steel silencer that takes the place of the stock muffler. It is built to add horsepower and torque and give a deeper, throatier exhaust note, and it is dyno tested. Its design makes a deep resonant sound for maximum output, with looks similar to OE. The silencer has a brushed steel body with a black powder-coated end cap, metal bands at each end, a mounting bracket and a clamp at the inlet. Inside, synthetic wool gives acoustic insulation and long life, a baffle core handles back pressure and efficiency, and a detachable dB reducer fits at the outlet. The nuts, bolts, clamp and core are all stainless steel, made of race-proven materials.
