Default Emissions are killing me. O2 sensor help

alright to make it short and sweet i have xpipe wit a straight pipe flowmaster 40, NO CATs, and now my inspections over due. I usually get hookedup but now i dont so i need to find a way or i have to pay 800$ to make it legit.

MIL Eliminators, they plug into xpipe and h pipes. Too my knowledge i have 4 sensors i believe, 2 in front and 2 in the back. Would these parts be able to trick the inspection computer. If it turns my light off and blocks the 02 code it should block there codes as well. If it does work, how many will i need? thanks

in addition, it says they plug into the xpipe and looking at my stock exhaust theres 4. So im not sure if this would work.

im assuming you have a 96 or newer car if ur worried about emissions (in MA anything 95 and older doesnt get emissions tested) but for my 04 GT (actually anything 96 and newer with OBDII) the guy doesnt even run the car. he just plugs the computer into the OBD port and if the car has any stored codes then it fails. if not then you pass.

a while ago he used to run the car on drums with sniffers in the tailpipes.

conclusion:

if you dont get sniffed nor a visual inspection(if you dont have cats you SHOULD fail right off the bat) then make sure the car doesnt have any codes. in other words yes do MIL so it doesnt throw codes. i THINK (dont quote me on it) that you only need 2 MIL's because what throws the codes are the 2 O2's after the cats.

when the difference in readings of the front and rear O2's are not within spec of the computer the CEL will come on. if you turn the rears off then the car thinks the cats are there and working fine.

or you can get a tuner, and turn them off, and yes all you need are the rear mil. don't know about going a 100 miles thing. before you do the install disconnect the battery then reconnect after your finish, the the codes should clear out.

or you could risk it...after you put them in, since it taked a day or 2 for a code to pop up, go right to the test before it has time to throw a code.

There is no question, if you're levels are being tested and you have no Cats, you're not going to pass. Plain and simple. The last Stang I E-Tested without cats was spitting out 10,000 Parts per million Hydrocarbons. The limit was under 100.
