it restricts the amount of exhaust that gets to the second o2 sensor. This gives it a higher AFR reading. This simulates the cat doing its job when its not there

how does this work? It just picks up less emmission gasses since its further back?
That is exactly how it works... (Correct me if I am wrong)
Very GOOD Post!!!! I have done the same thing with mine. I have been threw two state inspections and has lasted a year and a half. I have that Megan Racing down pipe by the way. Great job!
This works great, put it on when i installed a megan test pipe on my g/f's car last night, no cel. Sounds killer too.

so now lets say i do this, could it potentially cause tuning issues because the ecu is reading incorrect data and adjusting a/f ratio off of it, or does the ecu only adjust a/f according to the first o2 sensor?
i think im gonna try it.

The ecu only adjust AFR off of the first O2 sensor

I have a HX with a EX header an testpipe conversion now my header has 2 02 sensors top an bottom.an my cat has one after, my stock manifold had a honeycomb like resonator on it i might get some pics if need be,an the cat had one, so i have 1 02 bypass in the testpipe check engine light (STILL ON)..... I didn't drill it out could this be why???? an what would happen if i put it on the lower 02 sensor ????????/

Im so confused by what your saying. .......This is how it should be.
First O2 sensor in manifold closest to the cyl head
Second O2 sensor further down pipe , past cat converter( if you have one )THIS IS THE ONE THE FOULERS SHOULD BE ON AND YES IT MUST BE DRILLED OUT OR THE O2 SENSOR WOUNT FIT IN IT!
Third O2 sensor......... Unless its a wideband i have NO idea what your talking about
