The Arrow Thunder exhaust system is the most popular exhaust for the Brutale with good reason; it looks and sounds great and drops a bunch of weight from the bike! Available as either a full system or slip-on. The collectors are optional to make a full system, but the mid-pipe is required whether you want a slip-on or a full system. The silencer shell is available in dark aluminum, aluminum, carbon or titanium and the end cap is available in stainless steel or carbon fiber.
