I'm looking to relocate my O2 sensor off of my cat. I have a magnaflow from a mustang, but obviously, no hole for an O2 sensor. Can i relocate it upstream? How? Chop from another car's exhaust? Anyone done this successfully with NO straight piping and NO check engine light/ loss of performance/gas mileage.

 

How many o2 sensors do you have?

If this is the 97line like your info says you should have two.

The upstelream one is the important one
The one that is put AFTER the cat can be left out completely as long as its still plugged into the harness.

If you put the rear o2 sensor in place of the front, what are you gonna do with the front?

The front o2 sensor is THE ONLY sensor that the ECU uses to control fuel trims. The rear is ONLY there to monitor cat function.


You can also put holes for o2 sensors anywhere.

Go to any exhaust shop like Midas or something and ask then to weld in an o2 bung.

 

LOL

Get yourself a new O2 Sensor Bung and weld it in.

Upstream needs to stay before the cat (and as close to it as possible) while the downstream needs to stay after the cat (and as close to it as possible).

 

Too slow!

 

I will add that on the scale of "intricate questions" with "0" being a wrecking ball and "10" being a particle collider this question rates roughly a "2" or "Hammer".

 

I know you were.

I saw your post after mine and then your edit to combine them.

It's ok - we know the truth . . .

 

I see an edit on my first post, where is the one on the 2nd?

 

What is the best sounding exhaust for my 01,xj.

 

The one you most like?

Why are you asking that?

Don't you decide things for yourself?

Do you have any personal preference?

What you like may not be good to someone else.

 

The one you deleted Mr. Moderator?

I have a screen shot of the post-edit/pre-delete if you'd like to see it. Browser caches are fun like that.

 

Any that comes anodized in PINK. Pink sounds the best. It also looks the most hardcore so that is the BEST color for your Jeep as well.

 

Nothing was deleted at all, good sir.


Fact still is...the first response was still the first response.

 

My bad. You got the "Too slow" edit in before the time ran out.

Ahem . . .

Why are you asking that?

Im asking because I want a deeper sound. I currently have a cherry bomb exhaust in place of the stock exhaust. I also cut off the rear converter.

Bigger pipe? Different muffler? Or both?

 

Pink exhaust? Didn't know they made one? Who makes it? Is it hard to find?
