my megan test pipe comes with a pre welded bung for the a/f sensor but the problem is that its angled a litte under 3 oclock more like 4 o clock is this gonna be bad if i install it in there?

 

i have a megan testpipe with a regular o2 sensor in there but its at like 2 oclock... could you take the test pipe off and roatate it up to the next bolt holes... you no what i mean? then it would be at a great level... but if you cant do thatim not sure of an answer to your question sorry

 

If you install it horizontally (3 Oclock) or lower condensation will deteriorate the unit faster than if you install it at leas 15 deg over 3 oclock. I installed mine at 12 oclock completely vertical.

 

My Uego sensor has been at the 4 o'clock position for at least 2 years. Still works fine.

 

yeah i as thinking just flipping it the other way but it would be near the start of the catback now is that ok kinda close to the rear o2 sensor

 

Mine is facing 3 o'clock also....no problems.

 

well 3 o clock is fine but mine is under 3 oclock around 4 oclock so its slanted downward instead of being horizontal
