Up for sale is a brand new Dynoport Big Core Barker. I ordered it to replace my original one which was damaged, but never installed it and ended up just fixing my old one. I've never even had this silencer out of the plastic, just opened the box to make sure it wasn't damaged during shipping. I'm asking $150 shipped for it, thats about $25 less than you'd have in the same thing to order from dynoport.
