Test Pipes & Borla (Emissions questions)

Take it to a shop that has the equipment, and have them 'sniff' before you go for the emissions test.

If you don't pass at the shop, make the necessary corrections before going to the t6esting station.

 

I don't want to make you nervous, but I think there is some cause for concern.

1.2% CO and 220ppm HC is medium-strict, from my research.

Without cats, if your car is running rich my opinion is that you will exceed those values.

With no cats and running lean, I think you could be OK.

Do you have any information on 348 emissions "before the tailpipe" (i.e. before any catalytic converters can improve things)? These are published for my 308 both in the manual and on a plate on the car itself... That will be important information for you.

 

I think the car's emissions standard (for model year XXXX) is usually on a plate in the engine bay. I don't want to scare you, but my guess is you'll fail w/o cats.

I have heard that come counties have different standards than others (for example, in Illinois, I believe regional districts do not have emissions testing where as Chicago does). I am told it is possible to register a car at a PO Box/MBE in such a regional district and thereby avoid the test. No direct experience, not advocating the position, any and all other disclaimers etc, but if NC is the same, there may be a work around.

Alternatively, you could just get a couple of cats, put them on and run through the test. A decent muffler store should be able to sort you out. A cat is a cat.

 

NC,

Some folks, every year or every two years, put back their stock exhaust or cats or whatever, and do the deed. We carb guys in 308s can just swap in some really, really lean jets and change the picture significantly for a few hours on an as-needed basis.

The car may or may not pass without cats. All depends on the "raw" emissions of the engine, as indicated by the manufacturer, of a very tuned engine.

Nobody's telling you to take your 348 into midas. Put them on yourself (should be an easy do-it-yourself job, or a good learning job if you're new to DIY maintenance), or have a private shop do it. I presume you have a mechanic--that's prerequisite #1 for owning these cars. He'll gladly do it I'm sure.

Also, I doubt you'll get an exemption, unless there are regulations on this and you fall into one of their exemption categories. A low mileage 1990 Ferrari that can't pass emissions probably isn't going to get much sympathy.

Regarding the F-150, often times there is an age exemption. Some states, for example, exempt cars greater than 25 years old... That might be why you see some seriously old smokers out there. The thinking is that these are 1) Pre-EPA cars that didn't have a lot of emissions in the first place, and 2) Form such a minority as to have little impact in the overall scheme of things.

NC, emissions are a problem that most of us face. You'll get through it. See what your car puts out pre-cats first as a starting point.

In some states (Illinios) you can obtain a show car exemption. You need to have a special insurance with restrictions on milage, but not any more expensive. You that (at least in IL) get a 2 year exemption from emission testing. Check with your local testing station.
