Hi I have a 630 with the Apropovic single system. From what I have been told Apropovic had a deal with Husqvqrna and the parts are only available through Husqvarna. I have tried through dealers in Australia with no luck. I want the silencer cone to suit. It is LOUD. and will need a repack kit in about a year. Any ideas as to who I could contact in the USA? It is an awesome exhaust and saves a ton of weight as well as giving me room for a tool tube on the RHS. Thanks
