DPF delete only leaving Cat on

I want to do a DEF delete but leave the stock CAT and muffler on the truck. I know I will have to tune as well. I plan to stay at stock HP with a stock intake. My goal is to lose the DPF but keep the quiet exhaust and still pass emissions for Nashville TN. (they plug into OBD long as you dont have a check engine you are good, they don't know what to look for when it comes to the visual test) I don't want to blow smoke just dont want fuel in my oil and waste fuel during a regen. Truck has plenty of power now for my needs.

Has anyone done just a DPF delete? Pros or cons?

thanks

There are pipes out there that will do this, they typically cost more than the CAT/DPF combo pipes due to the flange design. Either way though you will still need the correct tuning to pair with the pipe, you can't just remove the DPF without the proper tuning. And even still it will smoke if you throttle it to heavy.

It won't smoke on low power settings. I TRIED on +40 Spartan and couldn't even get a puff of smoke.

Also even with a 5" straight pipe my truck is still quiet. You could get by with just a muffler and it will still be very quiet.

A straight piped 6.4 is quiet period, the exhaust having to pass through two turbine housings and turbine wheels is more than enough to muffle the 6.4 . Mine and every other deleted 6.4 I have driven smokes even on the no power added setting.

Thanks for the info guys, the main thing is I don't want her to smoke when I am pulling out of the emissions testing bay! I think I am going to leave the cat on and just do a DPF delete, then I can still pass a visual inspection. My truck even now 100% stock still gives a small puff, I just dont want to fog for bugs like I see the guys on youtube do!!

As long as you aren't mashing the throttle to the floor you won't see any smoke. If you drive sensibly you probably won't even see any. I run the hd300 on hot and at light throttle I have none.

Just don't punch it out the bay, cause I have an DPF-r tuner no extra HP and my truck blows smoke when I start to hit the throttle heavy.

Are you still running the stock muffler and tailpipe? Noticed any higher engine noise inside the cab?

I still got the muffler and stock tailpipe. It's loud outside my truck,but inside its stock quiet.

I'm not sure how much the cat will help with catching the soot, as that's the point of the DPF. Considering you can run DPF delete tunes with the cat still on tells me the cat it porous enough to let the exhaust flow as it should, so I'm betting it wont catch much soot. With my H&S set on stock (no power) It doesn't smoke with normal driving, and I have a straight pipe from the turbo back.
