Anyone use these with success?

Kooks Rear O2 Spacer Extensions

Moves the rear O2 sensors out of the exhaust pipes for more accurate exhaust readings. Helps prevent P0420 and P0430 codes on most vehicles commonly associated with the addition of high flow catalytic converters
PRICE: $20.00
I'm running the Long tubes with the hiflo cats. I have the rear o2's turned off anyway with the predator tune but I couldn't pass emissions with the stock tune or without. Could this be the future answer? Currently, I am eligible to register my vehicle in another county that didn't require emissions but would like to be able to pass. Thanks!:beerchug:

Or are these the same you can buy at your local autoparts stores AND do they work well?

Why not just do it right with a Predator?

Won't pass inspection

Yep, rear o2 sensors are normally disabled.

I registered my vehicle in another county though so I'm good on emissions for at least another year.

Thanks Al & Dredog!
