Last night had a young bloke turn into me while I was passing and hit the back of my bike. He only creased/dented the muffler a bit and left some surface scratching right along it which could prob be buffed out or something. I was chatting to a bike mechanic who said people generally replace the muffler in this situation, but I should bring it around for him to see. Was wondering if anyone has had similar damage fixed? how much? etc.. I realise it's kind of hard without a picture but I'll try to get one up.
