I recently put on an off road H pipe on my car. I purchased MIL eliminators as i was told to do. So I figured I'd go cheap and get some used off Ebay. Got the H pipe installed, and now im getting codes thrown at me! I've had from running lean to sensor circuit, to heater circuit problems. My recent codes that i got today were P0420, and P0430, which is Bank #1 and #2 Cat efficiency below limit. I'm firguring that this is a bad set of MIL eliminators. I thought I'd see how many opinions from people i can get to see if I am correct. No sense in buying brand new ones if it won't fix the problem.

Yeah, i know i can make them, but i didnt feel like cutting anything off my O2s since ill have to swap the H pipes next year for emissions. Plus, im TERRIBLE with wiring, lol.

as long as you can find a shop that wont give you **** about looking under your car the o2 sims MAKE u pass emissions (at least the computer part)


I pass emissions with my Off-Road H w/ o2 sims

Yeah, I won't be taking it to a shop to swap parts, i can do that easily. The emissions place here in Ohio actually check to see if you have cats, and they put the sniffer in the exhaust pipe, so i know it won't pass, lol.
