So I had this shop install 1320 Resonated Test Pipes on my 2013 G37s Coupe 6MT. About a week or 2 later, I got a Service Engine Light which read P2098. (Post Catalyst Fuel Trim System Too Lean Bank 2). I was doing some research and was worried about the car running Lean which I know is bad for the car, I brought it to the shops attention and he said that he some extensions would do the trick and that I should not worry. What do you guys think about this? Any advise or tips? Where exactly is BANK 2?

I also want to add that during the install, I believe the shop damaged one of the sensors, and I had to get a replacement. It was upstream I believe? The passenger side sensor close to the headers. After the install, there were no codes for a week or 2, then that was when the P2098 code came up.
Only mods during time of install was Beluga Racing Axelback. Again any tips/thoughts would be greatly appreciated.

 

Tbh most of the time u will need a tune to get rid of check engine light- every car is different- some cars throw a code & some don’t - I had similar motordyne art pipes & it threw a code

 

Bank 2 = post cat

Extensions may work. As it sits, car is not reading a large enough difference from bank one to bank two.

Tune WILL NOT fix this issue. Tuners cannot turn off the sensors. In the event the sensors are off, you will still fail emissions because the system will show as 'not ready'.

 

Bank 1= Passenger Side= Cylinders 1,3,5.
Bank 2= Driver Side= Cylinders 2,4,6.
Upstream "pre-cat" sensors are A/F sensors
Downstream "post-cat" sensors are O2 sensors

 

Thankyou for the reply.

 

Thanks for the info, do you think this CODE is bad and that if I keep driving with this specific code, then its bad?

 

Awesome thankyou for the info!

 

Nope. Doesn't effect health or performance. Just won't pass emissions.

 

Thanks for the reply!

 

Got the spacers put on today, hope the code doesn't come back. Heres a pic of before and after with and without the O2 spacer.

Did this fix it? I’m getting codes p2098 and p2096.
