O2 sensor

[toy fanatic78]

I have had a few headers for different na supras over the years.All of them have had the O2 sensor mounted in a tube that is a few inches long.Shouldn't the tip of the sensor protrude slightly into the actual exhaust stream to get a proper reading?

As long as the gas gets in. Though it's more accurate if it's in the actual stream.

maybe they mounted it in a tube to keep it away from the heat seeing as it right outta the engin or turbo. sounds possible. i wouldnt do it though.
