legality of egr system removal

**sonnycw** · 04.15.2012

is it legal to remove an egr system on commercial vehicles? I have heard it is. The only stipulation is if the owner sells or trades the vehicle it needs to be reinstalled before the sale/trade. Is this true?

There is NOTHING "legal" about removing an emissions control device from any vehicle.

BIG, EXPENSIVE penalties if you are caught.

This is not as easy as it may seem to do such a thing. What are you running a Cat C-15 or C-13? If so you could call Cat see if they will help you. I do know they have told people how in the past. Need to be good at welding and have a computer to hook to the truck as sensors need to be turn off and pulled.

The bottom line is that it is not an easy thing to do. However, if you do it, you could expect more power and also 1 to 2 MPG average better fuel mileage.

This is why the Emission control devices are such a joke. With every 6 or 7 trucks on the road burning fuel... anther truck on the road burning fuel is required... that guess what, burns more fuel. In essesence, more fuel is being burned at a ratio of about 6 or 7 to 1, due to this goofy emission control devices.

i have 14L detroit. Also did some research and found recent EPA rulemaking will eventually reduce diesel emissions substantially. The federal rules affect only new engines, and due to long lives of heavy-duty diesels - 30 yrs or more in many cases - substantially turnover of the existing diesel fleet will not likely occur until for 2-3 decades after the rules become effective in the 2007-2014 time period. my truck is a 2006 with an egr system so do these rules not apply to me because of the year of my truck and the time they started to become effective?

If your truck is a 2006 and has an EGR system (meets the emission standards that went into effect in 2004), then you must maintain that EGR system on that truck. If you disable the EGR system or remove the EGR system or in any other way render it useless or inoperable, then you are in violation and face still penalties from the EPA if and when you are caught. What is the likelihood of actually getting caught? Probably pretty slim...but in that unlikely event that you ARE caught, the fines will be more than you "saved" by disabling the EGR. If you read follow the links I posted earlier, the EPA takes into consideration any economic benefits you have seen when they determine the fine you pay. So, if you avoided replacing expensive components, the price of those components will be factored in. If you improved your fuel mileage, your decreased fuel costs will be factored in. Basically, it is set up so that ANY benefit you saw is stripped away several times over when you are caught.
