Will removing the dpf cause me to fail the yearly emissions inspection?

magnaflow or mbrp are what i would look at... and alot of people are running the same intake i got its just about the best bang for the buck

I see your running turbo back exhaust. Does that skip the cat all together? Will that cause it to fail emissions. I just don't want to make changes that I have to convert back every year to pass inspection.

it will fail emissions and where i live we arent tested but if you put your exhaust back on for inspection you will be fine. I did the dpf delete and gained 4mpg while driving conservatly. Feel free to pm me with any questions on the dpf delete i have packages deals if wanting to know what it takes and have done it to my truck.

My LMM is bone stock and I cannot seem to get over 13 on the highway, but it does weigh about 12,000lbs. And it has a big square bed attached to it. It did go up about 2mpg currently has 17,000 miles
