Prices can go from one extreme to the other on the BAY. I just scored a new OS #704 muffler for a .60FGR, for only $4 shipped priority mail. Shipping alone was about $5. I have been trying to get one of these for almost a year and always get sniped or just bid up past $40+ for a used example. These are getting scarce for a reasonable price.

I am still at a loss as to how this muffler went for only $4 shipped. I guess it was poorly listed, with poor description, and I was there to snap it up.
