So I want to order a downpipe but I'm confused by the options on the zzp site.

All I want is a catless downpipe, and the 1 o2 bung for the factory o2 sensor.

do I choose "offroad w/o2 bung" or "no cat, no o2 bung"?

The discription of the product includes an angled o2 bung, so if I think if I order "offroad w/o2 bung" then I'm ordering an extra bung.... but I don't want to order "no cat, no o2 bung" and then not have the 1 I need for the factory sensor....

I used to think I was smart.... the zzp website has changed my thoughts on that!

Thanks for the help in advance!!!

 

If u get an offroad dp then it has no 02 bung. If u get an offroad with an an 02 bung then it will only have one

 

Are you tuned? If so you don't need a rear o2 as you can disable the CEL for not having it. If you are not tuned or don't plan to be tuned, get one with an o2 bung and order a defouler.

 

It's just confusing!

Here is the description from the site:

This is a bolt in 3" downpipe for your '08+ Cobalt SS TC.

Our downpipes are made from 304 stainless steel. No worries about rusting or paint flaking off. It costs a little more but we feel it's worth it. All welding is done to the strictest of standards and bears a professional finish. Weld quality is higher than any other downpipe manufacturer and a sample of one of our welds can be seen here: WELD We promise our welds to be 100% leak free. Even the flanges are stainless, which isn't something most companies can say. When shopping around, ask if the downpipe is 100% 304 stainless, and ask for a close up shot of their weld. You'll know right away what true quality is and what it isn't.

Angled o2 bung for rear o2 sensor

Option 2: If you select "Add an o2 bung for wideband" it will come with a 2nd o2 bung so you can add another wideband o2 sensor for a aftermarket gauge. But keep in mind the factory primary o2 sensor in the LNF is a wideband o2 sensor.



So, is the angled bung standard equipment? If it is, and I order "offroad w/02" I'll have an extra, right? why do they make it so hard?

 

it's explained quite clearly on the site.

"Option 2: If you select "Add an o2 bung for wideband" it will come with a 2nd o2 bung so you can add another wideband o2 sensor for a aftermarket gauge. But keep in mind the factory primary o2 sensor in the LNF is a wideband o2 sensor."

so if you don't have an aftermarket wideband to install, do not select that option

 

I am tuned, and I know the CEL can be disabled, but the rear o2 on the LNF is also a wideband, so if I don't have it in, how can I get accurate logs?

 

Um...

I know I don't need option 2... that's not my question at all. I am confused with 2 of the choices in the "model" selector.

 

And THAT is what I was missing!

Thank you Andrew.

 

Only the front o2 in the o2 housing is a wideband.....
