If I slap kooks LTs, catted high flow y pipe and borla cat back what are the chances of me passing the sniffer? My instincts tell me none. Would it be simple enough to swap stock y pipe and catless back on if needed for inspection?

With lts and cats you can pass the sniffer with a tune, but you will not pass the visual and its getting harder and harder to get a dirty smog. You would have to swap to stock exhaust manifolds and y pipe to pass.

NJ doesnt do sniffer tests on obd2 cars

The stock Y will not fit LTs, unless you modify it. Even then, in a true sniffer test it won't pass as the cats will be much further from the engine and not get hot enough to be as efficient as they can be.

Although like blueshark said, I don't think NJ does an actual sniffer test. Just OBDII check and possibly a visual. As long as they don't look underneath the car, your setup will pass the OBDII check just fine with the right tune.

Your car is no longer subject to the sniffer in CA since it is a 2002.
