Second thoughts...

Well, I finally found in WIS that those little canisters are part of the "Secondary Air Injection" system on the V6, which pumps air into the exhaust when it's cold to get the catalytic converter going faster. From the description it gives it doesn't sound like those would have anything to do with a noise like this. But, looking at my picture, right next to what I thought was making the sound, is none other than the turbo blow-off valve. Would this be the more-likely culprit? I know it's original so it's got a ton of miles on it, and I know they tend to fail. Would it show any other signs though?
