You can buy his pipes on Ebay and there is a core charge. If you send your pipes no core charge.That was how it was when I bought a set got Wendy. I ended up taking the last baffle out of those then gutting Wendy's pipes too. Then I gutted a few more sets.

I learned all I need to know about life by killing smart people and eating their brains.
