hello just got a quick question on where would be the best location on the s pipe to weld my second o2 bung in for my AEM wideband . or does it matter i just dont wanna eff up this up at all


thanks for the help

 

i wanna have the best possible readding i can get knowing my luck i will put it in the wrong spot and screw myself

 

In the directions it says where to put it. I think it told me to put it about 30 inches down stream after the headers.
