Hey up people! I currently own a fazer 600 s2 2007. I am wanting to buy a new exhaust for the bike as the stock one is rubbish! My bike has a givi monokey topbox fitted. The topbox bracket goes around the exhaust. I need to find an exhaust I know will fit onto the bike and still allow the topbox bracket to fasten around the new exhaust. Any ideas people? I wasn't wanting to spend more than £450. Thanks in advance, Matt.
