gutting cat? yes or no

i bought a spartan tuner yesterday along with the dpf delete pipe. i also removed the muffler towards the end of the truck just before the axle. would it be worth it to remove the cat and gut it or is it a bad idea

If you gut it, you will never be able to put the DPF back on until you get a working cat. I would say to leave it alone until you buy a DPF/DOC delete pipe.

There is a difference between the DPF delete pipe and the DPF/Doc delete. There are multiple vendors on here that have the DPF/Doc delete pipes. That way you can take off both of them and have the delete pipe in place. This way you can keep your stock stuff in perfect shape incase you need to put them back on for waranty work.

A "delete pipe" just deletes the DPF. A DPF/DOC (cat) delete pipe deletes both together. It is a much easier way to do your delete, and results in the best performance.

I was wondering about this myself, so please forgive me if this is a stupid question, but how does the doc affect the dpf and it's regen cycle? Hypothetically what would happen if you had a stock truck with a dpf and doc but the doc is gutted?
