1FZ-FE Whistle

[Sc0-]

Seems that one side affect of the snorkel is that my "whistle" noise dissapeared when WOT. Anyone else notice the same thing, I thought the 1FZ whistle was related to the exhaust Y-pipe collector?

Or is it possible that I just can't hear it over the added horsepower awesomeness? (j/k)

The whistle usually comes from the stock muffler

Didn't notice any whistle using my FleaBay dorkel, but there is a quick inhaling sound at the bird feeder when I tip into the throttle

OK, after another drive the whistle is still present but due to the extra intake noise it is lessened a bit.
