P2A03 - Sensor outside range. The code which can be a number of things.
It may be the sensor is damaged (impact guns on the bolts can do this) or it may be that the sensor is detecting there are no cats.

 

Thanks for the input Tony. I havent had time to get under the car yet to inspect, but would it be the sensors on the cat or the sensors on the manifold?

Given, I have never touched the manifold sensors so I doubt it would be that all of a sudden. The sensors on the cats, however, I found that each one is a different part number. If that's true, it could be as simple as swapping the o2 sensors on the cats to opposite sides.

I have done research on code P2A03, and as you stated it can be mutiple things. I'll take some time off lunch to put it on the lift and check accordingly. Any further insight is appreciated.

Also, I did not use any impact guns during the installation.

 

These have been on my HR Z for about 2 weeks now and I love them. Sound great, no codes so far (soon to be tuned to remove codes that COULD pop up). I have 2 questions however

1) What codes should I remove to stop the CEL from coming on for removing my cats?
2) Does anyone notice any RASP around 2, 2.5k to about 3k RPM? Its only right here, and its not too bad. The second i hit 3k it gets super deep again. Just curious on if this is normal. We cut down the bolt, and my buddy did a little TLC with the heatshield to avoid any potential buzzing. I know test pipes cause rasp, so im just curious THanks!

 

Normal test pipes rasp to all hell most of the time, you'll get almost no rasp with the ART pipes.

If you're getting any now, it'll be the rest of the exhaust it's paired with, stock?

 

Bank 2 Sensor 1
Driver side sensor in the headers.

Try swapping your header sensors and see if the cel follows the sensor.

 

If you dont have a cel there is nothing to remove.
If you have rasp, it very much depends on the exhaust you have. Some do, some don't.

SOunds good, I just wanted to have them disabled (whatever the code is) when i have it tuned so i dont have to worry.

My fiance has been driving the car the past 2 weeks (and i on the weekends / evenings), just rode in it yesterday and it sounds like the very slight rasp is actually disappearing. Now it didnt happen until 2.5k when before it was 2k usually. Doesnt bother me at all, Im very satisfied with the product thats for sure

 

Thank you! Your satisfaction is our #1 design goal. Its also why other less innovative companies try to copy our designs.

 

I can't wait to get a set, a 1 or 2 more paychecks away!

 

Is it possible to just get a passenger side v2? I purchased a set locally from a guy that had a drivers v2 and a passenger v1...hate looking at this thing in my closet lol they're so pretty

 

Send me a picture of what you have. info@ motordyneengineering.com

 

how in the world did that happen??

 

hr v2 art pipes shipped to 92604 plzzz

 

Hit their website and it has a shipping calc on it, quickest response is of course to call if you need to.

 

I'm confused why you are asking for a price quote here, but are selling the exact same thing here:

shady shady, something is probably wrong with the ones hes selling.

 

did an oil change only to realize i have bottomed out the art pipes a few times.. .__.

damn the massive driveway.

 

Ouchie! I cringe and check if i ever bottom anything out, there isn't really anything under there that's designed to do so

 

so after 42 pages did anyone try these pipes with a turbo setup? is the piping just too small to be efficient?

 

Hey tony I just installed the ART test pipe on my 08 350z. I currently have weapon-r intakes and stock y pipe, with invidia pipe back. After throwing two codes, replacing the primary 02 sensor, and a UpRev tune I feel a lot of hesitation between 1-4k rpms. What are ways to get rid of this low end hesitation? Will adding a x pipe help? I gained only a 10 whp on dyno dynamics with those bolt ons alone. Any advice will be greatly appreciated.
