Not sure there shaker......
Kind of the exact reason why I've retained my stock set up.
I guess I'll find out come that 1st test. If I gotta throw back on the OEM set up, then I will.
Minor inconvenience in the overall grand scheme of things.
So, ummm..... yea
From the testing website:
Q. How often will my vehicle need to be tested?
A. Vehicles begin testing when the vehicle is four years old. For example, a 2003 car should be tested in 2007, 2009, 2011, etc. In certain cases, a vehicle may need to be inspected if it was not in compliance when acquired by a new owner, or when the vehicle is newly registered in a test area.
It took exactly 4 years for them to call my 08 GT500 in for testing. What surprised me was they did not just check for stored codes. They read all indicators to see if they are responding via the OBD-II port. I then connected it to an Innova 3130 and shonuff, it gave me the exact same (3) emission readiness indicators:
Cat Conv Eff - not ready
Heated Oxygen Sensor - Not Ready
Oxygen Sensor - Not Ready
Technically, it was not a failure, but they told me if it happened 3 times, I would be required to take it to a shop. Plus, the Sec of State sent back my registration application for a new plate sticker because they knew I had not passed emissions!
As long as you kept the catted down pipe and have a tune with the rear O2s turned on you should be good to go. I only mentioned it because a lot of folks do not know they check that all your O2s are functioning and there is no way to beat the system without cats.
