Question type: Car Customization

I have an 04 Chevy s10, I'd like to customize
my exhaust but I don't know what to do with
my rear O2 sensor without it throwing a
code & Check engine light. (Meaning
removing the catalyic converter)

I think u can get dummy sensor that say the air flow is the same with or without the cat but with no cat it won't pass inspection

There are adapter tubes out there that your O2 sensors screw into and reduce the Oxy levels to 0 just for your rear O2 sensors. Just google them.

and they are for off road only.

No big deal , have a muffler shop drill a hole & mount & weld-in a fitting & screw a O2 sensor in. Tube headers come with this fitting too, & some cat back exhausts.

My 350"/350 hp lowered sb sport truck. O2 sensor fitting welded-in ahead of the cat.

That won't work James, he's talking about the rear O2 sensor.

That's correct tennisshoes& in doing my homework it sounds like I need a wide band O2 sensor......but I don't know which one fits a 04 s10
