Well I did it, I cut the muffler off and had my local muffler shop weld a piece of pipe in its place, I left the resinator in , sounds really good , not to loud. the truck even seems to run smoother:peelout

If you have the 5.9 , then you can remove the cat and muffler with no codes or issues......except emissions checks...:w:
It will be loud though!If you have the 6.7,you'll need the dpf delete kit....:$:

Fill in your sig.when you have a second.....helps us help you.:thumbsup

It will definitely free up some of that back pressure, and should drop your egt's some. Good luck with the new truck.
