I just bought a new 426 and put an E-series pipe on it so I would have the spark arrestor. I am selling my stock muffler that has never been used. The bike was started with the exhaust on but that's it. It also still has a good useable coupler gasket. Anyway, if someone out there needs one, let me know. I am hoping to sell if for around $150 and I'll pay shipping. Or, how much is it worth? I can send pictures if you would like. Thanks guys, this site is great!
