Resistors to straight pipe a 2013

Do you guys think if I used 100k resistors to straight pipe my 2013 I would have any problems. Saw a guy on YouTube do this to his 2013. Just want to get your guys thoughts.

I think you would be the first to attempt it on here, I don't think the guy on YouTube has his truck is running right though. There has been some post on here and the general consensus here is the def is a must with CPU to run correctly so far.

I wouldn't be deleting everything, egr and everything under the hood would stay. I just want to straight pipe the truck. I know on the older 6.7's you could just use sims but these new 13's are tricky little suckers.

The ECM reads the pressure difference between DPF inlet and outlet, then SCR pressure etc and someone is going to "fool" the computer with resistors?

In theory if you find resistors that matches the sensor feedback at optimum conditions, meaning no need for DEF or regen, then who knows, it could work...

Following that logic, in theory, you would need X value resistor for DPF inlet side, Y value for outlet side and then something for SCR.

In reality, after working 3 years with Cummins QSB and ISB engines and emission systems, I would not go fiddle any of those emission system and someone claiming they have fooled 2013 DEF system with capacitors is BS as it might run for minute or two, but lets see after 6 months....

That's also what I was thinking because these new computers are way smarter than the old ones

Trying to put SIMS on a 2013 and hoping it will work is like someone putting gasoline in a diesel truck and saying the pump looks the same so it should work.

Totally different emissions system from the 2007.5 - 2012 trucks. You have to start from scratch.
