The standard Mercedes SLS is a loud little bugger. But it becomes downright insane with after market exhausts. Here Marchettino brings us a clip of a Mercedes SLS Roadster Hawk tuned by Hamann, featuring a set of titanium exhaust and upgraded engine. It also gets a body kit and an interior treatment which we don’t like, at least not in red. There’s no argument about the sound it makes though, especially on the overrun… that bang-bang-bang is just awesome.
