Electronic Sound Boom for All Cars

A sports sound boom, I don't know its brand name, comes with two outlets: one for sound and one muffler. It requires a complete control unit, which costs around 100 on Express, while some people sell it for 200 to 300. The boom came with the motor, but I haven't tested it, so I don't know how the sound is, nor have I tried the engine opening and closing completely. The boom is free of welding, meaning it's not hollowed out. The pipe size is 2.5 inches and fits almost all cars.
