DPF Delete with stock muffler and cat

Can you run a dpf delete, but leave the stock muffler and cat ?? I just regen'd 2 times on one tank and it seems to be fairly common for my city driving.. I would like to benefit from the 1-1.5mpg that a delete would provide, but dont want to deal with any added noise..

I just wasnt sure if leaving the stock muffler/cat but deleting the dpf would cause and issue.

I would use a tuner of course to take care of the electrical/cpu side of things..

What I want to know is are you guys going bung or no bung with the delete pipe? What are the pros and cons to either if any. Just placed my order for H&S mini, Flo-pro delete no bungs and AFE intake. 8mpg towing 10k lbs bobcat is getting a little stupid, cant hardly wait to hook onto 15k lbs 5th wheel this summer

Theres no need to cut them, they can be unbolted and replaced with straight pipes.

I was told that the stock muffler does very little sound deadening once the DPF and cat are removed.

This is correct, we have tested a bunch of different combinations of pipe sizes from 4" inch to 5" along with straight pipe downpipe back systems, our CAT/DPF/UREA delete pipes, to our delete pipes with aftermarket DPF back exhaust kits. The stock muffler does a better job removing hissing sounds then no muffler at all like the straight pipe downpipe back kits. The best combination we found so far IMO is a custom 4 to 5" CAT/DPF/UREA delete pipe built to run a 08-10 6.4 Magnaflow 5" DPF back kit with full size muffler. It may sound confusing but bolts right on and sounds great. We had this setup on the truck that went to Rudy's in NC this week for the open house/shoot out. It is completely reverseable for dealer visits if needed.

So...are you saying the 08-10 fitment can be mounted on the 11s?

Kinda with the correct CAT/DPF/UREA delete pipe, it's not just bolt in.

I have the 2011 6.7 and just want to know the most effective way to get a deeper sound out of this very quite diesel engine without spending too much.
