Well after spending the day looking, I'm sad to say I'm officially calling off the search. I have no idea where or what happened to this muffler other than I know I had it in a box with some cylinders. I even checked to see if I sent it to any one already, nothing. Reorganized the entire place in fact, looked in every container it could possibly fit, emptied every box...nothing.
So, I'm going to just have to say it was the JMS muffler bandit that struck and just go with that.
I'm very sorry that I misspoke to you about this, and I guess I better look before offering next time. With apologies, Steve.
