Hey guys,

I'm getting a bung welded into my exhaust for my A/F ratio gauge this week. My question is, where exactly in my exhaust do I want this hole put? I've heard on the headers, but I wasn't sure...

Thanks!

 

my tuner told me it was optimal before the cats , but not necessary .his second option was to put the sensor in the second cat and he would disable the code . I went with option 2 , seems to b working fine

 

Not sure about welding them, but I can't resist posting this:

 

Before the cats - so, on the headers would have to be the optimal spot?

 

seems I need to be on here more than the hrs I already am...I opened this tread to post it...lol...nice

 

I thought this thread was gonna go wild.

 

Yeah, no one made an *** of himself yet.

 

I had mine welded into the driver side exhaust manifold. Get it welded high enough so that the tip of the sensor does not point up in the exhaust pipe. It will collect condensation and foul out sooner that way.

 

Are you threatening me! I need tp for my bung hole....

Sorry OP... Hope u clear up your bung hole issue.
