| | Cadillac Owners Fanatic Cadillac(s): '05 cts-v  | | | | | Passing Emissions Test with B&B Headers and Xpipe?
Anyone with B&B headers and x pipe (no cats) know if you will pass the emissions test with this set up? I know states vary, I am in Texas which I think has the most lenient policy...any input or experience would be helpful. Ive got to get inspected by Oct. and Im wondering if I need to start looking for a "friendly" shop  Thanks guys! |

In Texas, I think you could give the tech's daughter a good rodgering and still pass emissions.
Now, passing it in MA is the question...

In Texas all of the original emission control equipment is supposed to be intact, the computer should show no emission-related DTCs, and the exhaust output put must be below certain thresholds. The second two requirements, in theory at least, are easy to enforce. Enforcement of the first one vary's simply because individual inspectors may overlook missing emissions equipment or fail to notice tampering with such devices. For example, at least one forum member has reported passing a Texas test with no cats. This obviously required inspector error. |

Even if they don't look for them, the tail pipe sniffer will likely fail it. |

Of course cats are required in every state. What the BigAndy is asking is if exhausts sans cats will pass the sensors.
In MA, my healthy '92 SHO passed sans cats...barely. |

It totally depends on the type of test equipment they use.
In VA we use a dyno only for older cars or "remote sensing" cars.
Anything newer than '96 gets what DEQ refers to as an OBD test.
Basically you connect a lead to the DLC under the dash and it checks the computer to see if the flags are set and if there are any codes.
Basically if the car has been driven for a while without clearing the codes and the CEL is not on it will pass.
If you have that kind of aftermarket setup then the catalyst monitors are probably turned off or you have simulators.
Out here you might pass an OBD, but you'd never make it on the dyno with the 4 gas analyzer.
If they use 4 gas on every inspection it is unlikely you will pass, if it is an OBD test and you don't see the CEL, you probably will.
I have no real knowledge of the testing they use in TX so I can't really say one way or another.
Good luck I guess. | | Cadillac Discussion Tools | | |
