header technical help

neilan · 02-11-2007, 09:29 PM

well i am about to order a thorley header and everythign to do my exhuast from summit racing.

One header has a 02 bung on the number 3 tube. I know this is not optimal as it doesnt take the average of all cylinders.

Am i better of buying the one without the sensor bung and welding in a bung in my exuast right after the flange?

I am thinking option 2 is better but i dont think my current 02 sensor wire will reach. If i remember correctly LCE had a extension wire but i cant seem to find it on there website anyone know about this or if the wire will actually reach to the end of a thorley header?

hmm thats odd i thought the o2 sensor was spoused to be atleast 4'' from the cat

nope on early 22re's there is only one. it is right in the middle of the exhaust manifold.
