I'm looking into getting the exhaust for my 2008 ram 2500 6.7 diesel,they offer it with or with out bungs in it,I'm going from the turbo back with a muffler a complete system!
What should I run with or with out?
Also 4" or 5"

 

I'd say its preference, with bungs is nice so there is no open or loose connections. Looks somewhat legal and for 4 vs 5 inch I like the sound of a 5inch more.

 

So I think I found my answer! If you are running the egr delete and a tuner you don't need to put the sensors back in!!

 

What I did on my truck is removed all the wires Follow the wires up on the driver side by the motor and you can unplug them all. There's no real reason to run bungs. You don't need them. But all the wires running back in plug easily.

 

Hi,
The bung option is there because it depends on what tuner you will be using for your Off-Road set up.
Some tuning requires that the sensors remain in the system, others do not.

For more info. feel free to give me a call.
Thanks,
