Formula 1 Motorcycle Exhaust And Muffler Systems

The mufflers on my earlier model bike were originally from Formula1, fitted by the previous owner and now due for repacking. I sent them over for repacking, and with a rattle and something loose inside one of them. There were dramas with AustPost and I ended paying extra for a courier to get them back to me. They came back still with the rattle and the loose something floating about. I wasn't given a refund for the AustPost freight I'd originally paid for (he got the refund and didn't pass it on).The guy doesn't answer emails or his phone. If you are into stories and poor work, this is the business to visit.
