What does it mean to you to purchase and install CARB (California Air Resource Board) approved performance products on your Cummins, Duramax, Powerstroke, or EcoDiesel? Well, it means a few things. First and foremost, it creates simplicity when it comes time for emissions testing on your truck. Instead of having to uninstall the product for testing, only to reinstall immediately after, you can merely leave your truck as-is and perform the test. If any questions arise during the test about the aftermarket upgrades you've made, you can merely provide the CARB E.O (Executive Order) Number and the inspector will move on. Further, it means that you're guaranteed a product manufactured by a company that has performed rigorous testing to ensure that the upgrade you've chosen will not have any negative effects on how your truck performs and can perform perfectly as a stand alone product. Both of these reduce headache and keep your truck running in better than stock performance.
So where does all of this come from and what does it mean? Why should you install CARB approved products, even if you don't live in California? The answers are both simple and complicated. The overarching answer, though, is that numerous states lean on California's rules, to include, but not limited to Colorado and Washington State, thus they take the mandates as set for by CARB, and apply many of the same standards to their own emissions testing. The next misconception of many is that these rules only apply to 2007.5 to current model years, essentially the release of Diesel Particulate Filters (DPF). Again, this couldn't be further from the truth, its just that its talked about a lot more on these applications. Overall, whether its a 12 valve Cummins, a 7.3 Powerstroke, or a brand new Duramax, they've all had to meet emissions standards of some kind, and by having an EO number, you are granted a hall pass, so to speak, knowing that the upgrades you've made will not cause the truck to pass an emissions test.
And finally, there are many products that simply do not even need a CARB EO number, because they're simply non-applicable to emissions, such as a DPF back or cat-back exhaust system. Because these products are downstream of any aftertreatment devices, you're good to go without any headache whatsoever!
