check out this link, anyone try this?
how did it go or would you recommend not going this route?

Looks like a plan...I may consider it if mine ever finally hard-fails. (Note: if you have a 2004, the diagnostic code is P0492, not P0416.)

Two caveats:

1. I've met smog-check people who were **** enough to squawk about anything that doesn't look stock. Those bright shiny clamps and/or the cut end of the old pipe might get their notice.

2. I would not recommend the method that reuses the old passenger-side pipe, as it puts a piece of rubber heater hose on the exhaust (hot) side of the check valve. There's a good reason the factory setup uses stainless pipe between the check valve and the manifold. You could probably put a compression or flare fitting on the cut end of the pipe and then a threaded coupling to the new check valve, but that makes the whole thing more trouble than its worth.

I looked at that procedure and considered doing it. I then thought about the fact that the original check valve lasted over 100,000 miles in the place it was, I then elected to pull the manifold off and replace the valve behind the manifold. I believe it took me about 2 hours to do the job. Just my opinion, wish you luck on whatever way you go.

Thanks for posting the link to the You Tube video. Interesting way to fix the problem.

i have an 01 and not sure if it will work but it seems that if you can relocate the part to a better more accessible location with out harming anything it would make sense.
thanks for the input
