Walker Exhaust 54487 Exhaust Resonator and Pipe Assembly e.g.

Ended up with two of these, and only can use one per decade.

I can fairly easily get this to Rockford, IL or Ann Arbor, MI without too much trouble. It's still in the shipping box, so I could ship it. Guessing shipping is silly expensive. But send me a zip code, and I can see what I can do.
