I did consider fabricating my own collars, but for $25 these at NP became a no brainer.
Great pics lightfoot, thanks!

Drifting
I've had a set on mines for more than a year. I also have them just slightly open, but one of my valves rattled pretty loudly at idle when it was just barely opened, so I had to open it a bit more than I would have wanted. Then, you get kind of a motorboat sound. I fiddled with it to get it right at the point where the valve didn't rattle, and I like the way it sounds.
