    Expansion chamber / header for a '99 KTM 300exc

    Mine's been fixed so many times that I'd rather just replace it. Would prefer not to spend $300+ on a new one, not that there are any even available. Nothing used on eBay either. Anyone have one sitting on the shelf? I think '98-'02 250-380cc will fit, but I'm not positive on that.

    Something in the back of my mind says you can go later, but you also have to replace the silencer at the same time as they went to a larger ID for the connecting flange, otherwise the mounting points are the same?

    You might be right; I'll try to look into that. I wouldn't mind replacing my silencer too.
