And the answer is...(warning - 5 pictures)
"What is - there's something else bad also". In an ongoing attempt to find the source of a buzzing/scream (I have used many terms) related to heavy throttle input >/=~4K RPM, here's the result of checking the TBB for tears and the resulting elimination of my "gas passing" or "could play this like a trumpet" noise.
The tear was well hidden.

<big sigh of relief> Thank you, thank you, thank you.

Same place many find the tear.

And something new (to me) on the opposite side.

Although this did remedy one symptom, I still have something else causing the buzz/scream. I found a very slight amount of oil in the left turbo line (right turbo if facing the front of the engine). I called my service writer who asked some techs. They told him they see that most of the time on the left turbo, and it was normal (?). When I saw it, I just said "breaking turbo", but I'm up in the air about that now. The dealer gets to check it all out in the 4th, so we'll see then.
I popped a clip of some kind off when I pulled the left large plastic riser pipe out of the TBB. It's a channel about 3" long, 1/4 " wide, and 3/8" high. It has the male side of a clip on both ends and it appears a wire or tube may rest in it. Any ideas where it came from? Hate it when I end up with extra parts.

Congrats on your efforts, those tears are often hard to spot without close inspection..
As far as your question about the part... can you post a pic and I will get under the hood and see if my 01 has same part (there are differences)to let you know where it came from.

Samco TBB or AMS kevlar taped "T" TBB
had the AMS TBB on for a bit and was fine. Cost is $89 with their special spring clamps.
Or you can go high end and get the APR Bi-pipe at ~$350.
You maybe be able to find a deal on a used APR Bi-pipe since some cars are being sold and they are reverting back to stock form. Watch the adds!! : )
