W body downpipe So I saw a thread on it before, but now I can't seem to find it. So . . . I just started this one. Someone posted a link for the catted W-body downpipe, I followed it and emailed the store a question on a common issue. Results:

Noticed you have listed a downpipe that would work for my 2007 Impala SS on your website. It is listed as a "3" Bolt-in Downpipe (5.3L V8 Only) [WBS-53D] " . Does this throw codes with the O2 sensor. Are their simulators to help eliminate this? Thanks

It seems hit and miss. Some cars throw a code here and there while others don't ever. The good news is that we have extenders for the rear o2 that help trick the PCM into thinking there is no problem.

Thoughts? Opinions? Anyone tried one of these extenders?

I understand you, and while I agree with you. . .my main question was about the extender. . .I wasn't explicit enough. I didn't know if the extender worked or what it was. . .it doesn't make sense to me. I don't have a laptop, so an HP tuner isn't real freindly for me. . so I am looking for other options to increase performance without needing an HP to take care of codes and such.

Maybe Curt could tell you about the extender? Also, its just not the P0420 code you will throw, but any bank 1 sensor 2 codes will be thrown aswell. There is a long list of them.
If you need a laptop, I have one cheap I am willing to sell to you. Trust me, you are going to need codes deleted sooner then later if you go with a high flow cat downpipe.

The extenders just trick the PCM into thinking the O2's are there in the system, when they are actually located farther back than they should (Exhaust Bank 2 on most tuners).
