Emissions Testing
Can emissions test pass with a straight pipe (cat, muffler, resonator delete) IF the engine is perfect and is nothing visible coming from the tail pipe. O2 sensors are spaced out.
They are using a rod to test for emissions. Anyone here pass emissions with a straight pipe ?

I'm going to guess no if the cats are removed and they actually do a sniffer test. If it was a visual test and you had the cats in place just cored out then yes I have passed in other vehicles that way. In Denver they put your vehicle on rollers and use a sniffer while they run the car up and down through it's paces so no chance straight pipes would pass.
