Pfadt Headers w/ Cats > Anyone get codes?
I am about to have a set of Pfadt headers w/ cats installed on my 2011 GS / A6 with NPP.
No other mods done to the car except an Airaid intake.
Just wondering if anyone here that has these headers on there C6 experience any codes and check engine light after the install.
Thanks,

Even if the rear OEM O2 sensors are re-installed in the Pfadt catted X-pipe, does it still throw a code that turns on the check engine light [unless] the code is permanently turned off in the computer?

Thanks ... Looking at photos of the Pfadt headers (at least the catted version), it looks like there are bungs drilled for the rear O2 sensors to get reinstalled.

On my car the shop installed both fwd. and aft sensors but then, as part of the tune, turned the rear sensors off.
It's my understanding that after header installation if the aft sensors are installed but not turned off a cel will almost always occur.
In the eight months I've had my headers the car has been trouble free over about three thousand miles and three HPDEs.

Larry ... Thanks for the reply. As many people here that have purchased and installed Pfadt headers since they were introduced, I am surprised nobody else has responded to this thread.
BTW ... Since they put your car (is it an LS3?) on the dyno to tune it ... what RWHP did you get after the header install and the tune?
A6 or M6?

My objective is to reach 550-560 rwhp but first need to upgrade brakes, suspension ect.

Thanks Larry ... wonder what a bone stock 06 Z06 will normally put down on the DynoJet (SAE corrected)?
I am thinking a 13% loss which would get you 439 RWHP (505 -66 HP)
You dyno'd 487 which would be an increase of 48 RWHP over the 439 for the headers, tune, mufflers and CAI. (very nice)

Yes, I was happy with the results. The car is noticeably more powerful. On the back stretch at VIR, when I got Oak Tree right, saw an increase of eight to ten mph from last year.
