Should I assume that an 84 carrera w/ a cat bypass will not pass emissions in NoVA - even if it passed in Texas not too long ago?

[Clarke]

Not likely to pass. If the inspector is doing his job it would fail for a visual inspection of the components, regardless of what comes out of the tail pipe. The cat has to be there for the safety inspection as well. Does Texas put the car on a dyno to do the test?

[Rick K]

Not sure about Texas. I do know that the past couple of times I've had an emissions test done in NoVA, the car has not been on the lift for a visual inspection - nor would I want an inspection station putting my car on the lift.

Rick -- I believe some here have passed the tailpipe test. And I don't think anyone here has posted about failing the visual (I guess most techs aren't familiar enough with the old 911 exhaust systems). Clarke is though, so stay away from his garage

I'd done the sniffer test with my '85 Carrera with a Fabspeed cat bypass, stock chip and a dual out muffler. It failed. I returned with the cat installed and it passed.
They didn't say anything about failing me visually on the cat pipe.
SC's are much easier to get past emmisions with out cats because you can lean them out.

Omar down the street seldom checks!

X2, but of course Ted and me were testing cars not for actual use on the highway!

Who, me? Yes I am an emissions inspector, no we don't do them at my shop.

I couldn't pass with my SC, so I borrowed Mackpipes' O2 sensor and passed. I have to wait until January and I'm done with emissions, the car is a MY83, so that's 25 years by my count....please someone tell me I'm right on this.

You're right, Va Steve.. I think emmissions inspections are every 2 years in Nova.. at least thats what I was told. So, if an '84 can be passed just once, it could be for the first and last time as well. Course, after 25 you can then change to antique tags, which impose other limits on vehicle use. I *think* if you keep "regular" tags on it, you must still pass safety and emissions.

My understanding is, not emissions, but yeah safety. It'd better be!
