Looking at a car with this code. Super clean car and has a catless down pipe and says the code is on because of that. Any way to get that code off? Thanks

O2 extender or remove via HPtuners

Or get an oem downpipe

I'm having the same issue after installing a high flow down pipe. After doing some research I found my best option was a defouler from modern performance, $36 shipped I believe but my cars also untunable until I swap pcms.

Zzp also sells it

O2 Bung Extender - Exhaust

Wish I saw that sooner. Pretty sure it's cheaper and the dp is a zzp lol oh well

My TurboXS pipe with defouler still killed my O2. If you don't need to pass smog it's not a problem and won't affect anything.

I got the turboxs and it's worked fine for me

Anybody have a link on what to get? And will it definitely work? Thank you all!

Which downpipe does it have? It could very well have one already.

A defouler doesn't always solve the problem like in my case. Either replace the O2 and hope it doesn't happen again or get it tuned out.

With the downpipe you're not really gaining anything without having a tune anyway.
