O2 sensor extenders.

O2 sensor extenders.
Hey I just recently installed an ecs tuning 3 inch test pipe onto my 1.8T and after a couple days my check engine light kicked on.
Now some one told me to run O2 sensor extenders to get rid of the check engine but I'm a little hesitant because I'm worried about them leaning out the motor especially when the car hits boost. Has any one else used them? Are they worth it? Or is there a better method?
Please let me know. Thanks!

The secondary O2 sensor is the one which will need to be spaced out, and the only purpose for this sensor is to make sure your car isn't emitting too much emissions. The primary O2 sensor is used to control fueling.
This is what I use with a high-flow cat, with success:

Thanks guys for the feed back. But I'm still worried about the extenders because they do lean out the fuel to air which is something I'm really worried about.
But as far as the re-tune idea. I have been wanting to get the GIAC re-tune. Would that take care of the problem?

Nope.

This, well almost. It's there to see flow to see if the cats working. If it's to high or to low, you get a cel for a leak, damaged, or clog cat.

You didn't post the year/engine code of your car, but FWIW I'm using an e-bay knockoff of that 034 spacer and its too long. I'm getting a "your secondary O2 sensor is dead" code instead of a "your cat is dead" code.

Close enough in my mind it's only used for emissions purposes 'cuz you can't have a clogged test-pipe and a clogged high-flow cat is rare.
