Upgrading a Fz6r exhaust

So I want to get a better exhaust for my 2016 fz6r but like my gsxr it seems I can’t just get a slip on it look like I’m going to have to spend 500+ for a new system at least that’s what I think anyone know a way around spend that much money or if I can make changes to the current exhaust because the current one sounds like a vacuum cleaner. via /r/motorcycles https://www.reddit.com/r/motorcycles/comments/dfgtta/upgrading_a_fz6r_exhaust/?utm_source=ifttt
