Emissions test

I just bought a 03 Mach with LT headers and H pipe with cat back..it was SCT tuned. Will this pass the OBD test? The check engine light is not on.

depends

does your state allow long tube headers
does your state allow offroad midpipes, no cats
are the monitors "ready"
call a smog shop and ask them
if you reset your battery recently, you will have to drive the car 100-200 miles to "clear" the monitors from the computer

GOOD LUCK

No fault light could mean the 02's are turned off.
Most states require all systems report ( ODB II ) ready or active.

So it will not pass?

In VA you are allowed 1 unready monitor but I believe it can't be for the CATS. It looks to be the same for NC, although it doesn't say anything about the CATS. You will probably have to have cats for the visual tho.

Following from this site https://deq.nc.gov/about/divisions/...m/emissions-inspection-results-information#G4

1. (1) - for all 2001 and newer model year vehicles
2. 1. The vehicle is rejected from receiving an emission inspection because it has too many "not ready" monitors, exceeding the acceptable limit.
   2. The customer attempts to get the vehicle's monitors to set by performing any of the following steps.
      
      1. Repairs, and/or
      2. Normal Driving (daily driving habits, i.e. trips to store, work, activities, road trips, etc), and must be documented by a reasonable mileage change between the first and last VIRS or
      3. A manufacturer's drive cycle may be conducted in place of driving the vehicle for several days. The drive cycle performed must be presented to DMV personnel.
   3. The vehicle returns for another inspection and again has too many "not ready" monitors, exceeding the acceptable limit. Another Not-Ready Rejection VIRS will be issued. At this point a "not ready" waiver can be issued.
   4. Owner takes the two Not-Ready Rejection VIRS to the local DMV office along with the manufacturers drive cycle, if one was used. If a "Not Ready" Waiver can be issued, DMV personnel will make the proper arrangements with the inspection station where vehicle will be inspected. Under the supervision of DMV the inspection station will proceed with the OBD inspection making special allowance to complete the emission inspection.
   5. The vehicle must pass the visual tamper and safety inspection portion of the emission inspection before a waiver number can be entered into the analyzer
3. There are different scenarios when a "not ready" waiver can be issued. Please contact yourlocal DMV office for specific information. Below are the general procedures for the "not ready" waiver.

If your location requires a visual instection, long-tube headers will not pass. We would recommend calling your local DMV for more details on your states smog requirements.
