There has been a problem for a long time putting smoke on an engine running canister mufflers.

With stainless steel headers there is no real good place to install a smoke fitting. Some canisters come with a smoke inlet fitting, but when you introduce the smoke oil into the muffler you've lost a lot of the heat that makes the oil smoke, and from what I understand it can develop into a gooey mess inside the muffler.

I asked a machinist friend to make up some 3/8" thick aluminum flanges that are the shape of the exhaust port, we did it for the TOC-53/TMM-106 and also for DA-50 size ports.

Now, here is the embarrassing part. Somebody called me a couple days ago and I told him about this and he wanted one. The problem is he caught me while I was on my way somewhere and I failed to write it down. I have no idea who it was.

So if the guy who asked for a smoke flange reads this, please call me back.
