Full Exhaust Systems and Sniff Tests
Hey guys, it has been discussed here and there but never in full detail, but I was wondering how those with full exhaust systems like Akrapovic, Ericsson, AA, etc. are getting around "sniff" tests during emissions testing. Here in PA we have to pass an emissions test each and every year and that test includes a "sniff" test and I can't figure out how anyone in a state with the same testing could have a full exhaust and pass emissions?
I welcome a good discussion on this, with anyone and everyone chiming in.....thanks! Cheers, e46e92

There is no exemption for new cars? What a scam.
Even in California new cars are exempt from emissions testing for 4 years.

I have a catless and unresonated x-pipe with remus race at the end..
you just gotta know where to go to get it passed.. But yea - it's definitely annoying that we have to get emissions checked every year. |

Just Keep the Stock Exhaust, and when the time comes swap the exhaust to Stock then after ReSwap with the After Market Exhaust
Simple

I had my HFCs put on after my inspection, so I have a year to figure things out. It may still pass with the HFCs - I'm not sure. I concur that swapping exhausts is not at all simple without a lift. |

The OP's question is a common one for those who swap exhausts. If you have a FULL exhaust system, including HFC's (or a cat delete), you cannot pass an emissions test. It's that simple. All these exhaust systems are labelled "off-road use only" for a reason - they fail EPA tests or were never presented for certification. Simply doing a visual on the car will cause an automatic fail. Just changing a muffler won't be a problem, but going over that will cause a "fail" on any test that is HONESTLY conducted. I agree the test is B.S., but if you live where they have one, you have no reason to complain about failing the test when you modded the car knowing full well it would, in fact, fail.

I changed my full exhaust out in half a day in my driveway on jackstands by myself. If you are worried about emissions testing move somewhere else or remain stock.

How's the sound inside the car? I have an RPi catless X-Pipe ( no primary or secondary cats) and I was thinking of going Remus Race or Sport, still don't know since this is my daily driver.

I am curious to know too.
In Maryland the tests are performed by state (who actually employ non-state-government workers) run emission testing stations. For new cars they just plug in a harness to the OBD II port and a few minutes later the printer spits out the report. Only cars that don't have the new OBD II port get the rectal exam, er, I mean, sniff test. So, I'm wondering if as long as your ECU is not reporting an emissions failure if this would pass in Maryland?

sniff tests are definitely annoying... i am in quebec where they dont conduct sniff tests on cars unless its a really old car and u were asked to get it inspected... i am planning on moving to ontario where they do sniff tests... hence i decided to hold off on the x-pipe and just go with a cat back exhaust for now...

I may be in the minority here but I don't see why many want to remove the cats and make a smog machine. Between the smell and the pollution, is it really worth it? I am not a crazy tree hugger (hell I drive an M3 LOL) but cars today perform so well, even with emission controls.

How do we know that the fabspeed will fail the sniffer? It may, I'm just unaware of anyone that has actually tried. In the fall I was able to go over 1k miles before I got a code, so that is plenty of time to pass all the readiness tests in the ECU - so the OBD-II will pass. So there is a *chance* that it would pass...maybe? : )

If your car is new like others have said you don't get "sniffed" just plugged into your OBD-II.
So as long as your tuner turned the codes off for catless (mine did) you will pass. They may say something about the visiual if they actually look. In my experience you can find the places (like others have said here) that will pass your visiual without saying anything. In regards to why would you want to run catless it's an HP thing. They restrict HP so if you have mods then you want to remove them so you make even more HP. |

For PA, you'll want to look here: http://www.dmv.state.pa.us/inspections/emissions.shtml and here: http://www.pacode.com/secure/data/06...hap177toc.html and call the station to be sure. |
