well, i installed my off road x pipe and headers last week. finally this week my check engine lamp popped on. P0420 and P0430 cat efficiency below threshold. i currently have the non-foulers in but it doesnt seem to change anything. i have an SCT tune and i know i can get a tune to shut off the rear O2's but im going to wait a while before i get another tune written.

I was looking at getting some O2 extensions from Casper electronics for 30 bucks and making my own. i cant seem to find the plug connectors for a cheap enough price. from my research, its about the same price to buy the components and build the extensions as it is to just get the prebuilt extensions.

Specializing in automotive interconnect and wiring systems

from what i am reading, you use a 1M ohm resistor in soldered into signal wire and jump a wire (forgot which one) to the sig wire with a 1 micro farad capacitor. supposed to keep the correct peak voltage and filter out unwanted EMI.

has anyone done this?

Think I need to try this too. The doubled-up anti-foulers aren't working for me
