Emissions Test with Catless/Catted DP

Hey guys, anyone here do an emissions test with a catless/Catted downpipe? Would catted be less likely to fail?

The emisssions test is an obd2 check. If you do not have any emissions codes showing and a CEL, you can still pass it.

Your emissions monitors have to show as ready, so you cannot reset the codes just before you go for the test as they will show as not ready. You will need to do some driving and different sensors will show as ready at different mileage

Ah okay thanks for that. Any way to trick the system then? I know flash tunes can get rid of CELs but not sure about emission errors?

Flash tunes can set the monitors to always show as ready, but they won't post that information publicly
