Damn. I took the DB Killer out of my Wings can yesterday morning before going for a ride. This morning I decided to put it back in. While putting the screw back in it fell off of the allen wrench and disappeared into the innards of the can.
I guess I'll leave it out. Not really too loud, and has a nice deep tone, especially on overrun. I can get another screw if I want to put it back in. I hope the old one doesn't damage anything rattling around in there.
I wrote to Gorazd and naturally he responded right away. He suggested using a magnet, which I had already tried but he told me the screw & washer would be right at the lowest point of the end cap...
With a strong rare earth magnet, I could hear first the washer and then the screw snap against the inside of the CF cap when I held the magnet against the outside at the lowest point. Then worked it up the side to the hole, and they came out!
So I went to install it again... dropped the screw inside again.
I chilled the hex wrench and the screw & washer, then put a little dab of grease on the head of the screw to hold it in place. Then I was able to get it at the right angle and screwed it in.
I like it fine with the DBK in, so I will leave it in. I have a Coober Power Kit arriving Friday, so I hope it will be a great match with the Wings!
