PostSubject: Passing Emissions with LT headers   November 18th 2015, 12:05 pm

I live in McHenry County, and as I understand it, they do OBD for emissions testing. In theory, id the car does not throw any codes, passing emissions should be no problem.

However, I would like to hear from fellow members what their experience is with modified cars an passing local emissions before I go drop $$ on a set of headers, etc.

do you throw no codes because your 02 monitors are turned off in your tune? or do you throw no codes with the 02 monitors still functioning in the tune?

if it is the first one i mentioned you won't pass, if it is the second one i mentioned you will pass.

Interesting. In that case, maybe the Kooks with their green cats are the way to go.

Based on what you describe, it sounds like the OBD test would reveal the O2 sensors being turned off, which as I understand it is common to prevent CEL's.

You can get an emissions tune that will allow you to pass. Had them on my Jeep SRT and passed, I know a couple of jeep srt guys that passed with no cats and had a turbo on their rigs.
I know a shop in Huntley that can do the install, just texted him and asking for a price
Make sure you use OEM gaskets not the shit box aftermarket ones.
