Used MagnaFlow 13219 3" In and out Reversible Offset / Center Stainless Muffler.
Part is used, but I have cleaned it up in the blast cabinet. No internal or external rot. Pipe Ends are good and not crushed from crappy clamps. Loud muffler.
Asking $55 plus Shipping from 15642, PA
Sorry I only have the one, not a pair, as it was on an inline engine.
Finish is satin / matte from bead blasting and cleaning the outside.
I added a weep hole under the center outlet than can be welded or plugged if you need it to be.
Pictures give overall dimensions and part number.
Comes with Original box - woo hoo!
