A set of downpipes like discussed in the thread would add to your issue. You have to run defoulers even with the catted pipes

What He ^^^ said.. No foulers were only about $20 and cured the issue. You can see the info on what I used above. BTW I went with the aftermarket pipes Because of the CEL code P0420.

Did you just put the no fouler on the 02 that goes into the cat?

I have dumb question. IF you don't do a tuner, will you gain any power, or does the computer limit it no mater what you do?

On the two that go on the cats, yes.

I found the nonfouler to work. Put on roughly 5k miles since the install and no CEL yet.

Stock exhaust, CVF downpipes with the wider turbo adapters. stock everything else.

What have you noticed so far with just those mods? I have stock exhaust and just the adapters on. Dealer had to replace a cat so I threw them on.

Put on the CVF downpipe along with bigger adaptors on my 17' 3.5. Such a beautiful product but it does throw a CEL.

Just put these on http://www.bigdaddiesgarage.com/mini-cat-cel-fix.html today
Hopefully that fixes it.
