Will the Speed 6 pass Emissions/Smog with a test pipe?

[desertmike680]

Here in Las Vegas, our smog check is done by plugging the car into their computer, not by a sensor in the exhaust. With that, by having a test pipe installed, would that ultimately fail the car for the smog test? I'm honestly thinking no being that the car is being plugged in. Hence thats the only exhaust mod I have.

As long as it doesn't throw a CEL, it should be fine. Seeing as how all the O2 sensors are on the downpipe, u should be good with ur testpipe.

well find an obd scanner and i think you can see if the checks have complected.
