I understand the majority of us are HPTuned and have no need for such, but we recently swapped a header and catless DP on my buddy's SS/SC and being he isn't tuned at the moment I utilized this trick that I've done with success in the past.

It utilizes a $5 anti-fouler pack from Autozone, one drilled out with a unibit, and the sensor fits snug into that one, and the other one serves to space it from the stream (undrilled limiting gases from reaching it). Ultimately this tricks the car into getting less of a reading, maintaining the factory sensor, and not receiving a P0420 code.

However you also need est. 2" of space which he had on his aftermarket DP, on my modded stock DP I didn't have such, so the one I drilled out for my car went unused.

$12 shipped and it's yours, have access to a drill? Feel free to take the advice above and DIY.

That's what my buddy has and it fit great, you just need to check the clearance.

Me too, ZZP really needs to change their product description.. I've had at least 5 codes from this DP, and I have replaced the o2 sensor once. I saw someone else complaining of the same thing, they said they contacted ZZP and they just told them to delete the code.. I am not voiding my warranty with software to delete a ******* code.

sub'd Let me know if this does anything for this dp.

you said you have a modded stock dp. did you just gut your cat? and you didnt have the space to do this?

Cut it out, replaced with pipe.

We did it off the car, so it was a hair off at the DP/exhaust flange, which also tilted the bung up. It all tightened up, no leaks, and I adjusted the rear hanger to fix it and all is well.

My buddy's ZZP bung was angled enough where this could extend the sensor slightly out of the tunnel.

i read this yesterday and went straight to autozone picked up the parts and statrd back home and got my car on the lift. i have a stock dp that i gutted and i love the sound it gave with my gmpp catback, but hate the cel. i was able to get one of the foulers in but not 2. getting rede to go to a friends house to have the cel cleard and then the drive back home will indicate if the one anitfiouler will work or if you must have 2. hopefully the 1 is enough space and it will not throw a light

Thing is with one, you have to drill it out. With two, you drill one out, leave the other untouched, thus limiting more gases. However I too wondered such, good luck.

EDIT: I wonder if a 90' pipe fitting or such would work for clearance-stricken issues.

I had mine tuned off tonight, so I'm pleased.
