Tricks To Pass Emissions?

That guy's o2 thing is essentiall spacing the o2 sensors out of the exhaust stream. In the same manner as say, covering up half the sampling tube in your MAF meter, they'll see less flow, and tell the computer everything is a-ok instead of telling the computer you're running lean. Pulse width will stay short and you'll run lean. Kinda a pita way of doing it though but perhaps the most effective.
I agree to that, my car could use a tune-up but I had a short window to get the car tested before I had to go back to school. With the GTP I got through the test like I needed to and Now that I passed I have the time to give the car a proper tune-up
The O2's work via toggling back and forth, and the computer looks for this switching. If the O2's are recessed, will this not affect their ability to have the signal switch?
The O2's are pinpointed in such a relatively lean range of the stoichiometric spectrum - I didnt envision trying to fool them doing a whole lot anyhow. Now hosing with the air-flow signal at the MAS could definitely cause some lean issues.
One more thing: I'd further add that if this O2 thing works and the car runs lean due to having manipulated the O2's: if one goes overboard and the O2 switching and amplitude aren't great enough, the car can go into FMEM (rich) and trip a code.

Man I'm glad my car is exempt.......I am sure NY will change the law sooner or later and put the meat hooks in my side!
