! I was gonna make the same solution for this months ago. I could never test it cause my car wasn't running. Damn, i was gonna charge like $20 for each thing too 
I think I even told you I had something in mind slow

...ya, I remember you PM'd me but that was after I had already made this post...it just keeps getting used and responded to...cause it works
And to the guy with the Venom NOS...like Slows said, the kit uses the primary O2 sensor to get the lean/rich readings...this fix does absolutely nothing to that O2 sensor as it is in the "header"/manifold...the rear/secondary O2 sensor's only purpose is to see if the cat is functioning properly...

BTW how LOUD is it with test pipe? I thought it would be better to ask here.
I have Amuse Dual right now..and I like to attemp this mod with Amuse Ti test pipe. and before I pull trigger I like to know HOW loud this can be...

The O2 sensor is there for a reason. With the help of this sensor, the ECU can adjust the air/fuel mixture to be optimal. If the O2 had to result faulty the mixture will be either lean or rich therefore degrade economy and performance at the same time.
I would be cautious fiddling with such sensor, but on the other hand am not sure if the sensor situated in the CAT is the one that does the role mentioned above. There is another sensor situated in the Manifold too.
If the Cat O2 sensor is there to spy on emission then another way out could be possible. The O2 sensor sends voltage to ECU, the higher the voltage the worse the emission is. So cars running without a cat have high voltage right. What about fixing up a resistance in series to the wire of the O2. This will reduce the voltage sent to ECU and acts as emission is as it should be.
Hey am not an expert on either cars/sensors or emission so don
