Anybody remove their CAT and hammer a pipe through it? Thinking about doing this and removing the stock muffler and replacing it with a Donaldson 51. I would do a CAT delete pipe but I dont want to deal with the engine light coming on.

You wont get a light on a 5.9 only the 6.7

I thought there was a censor in the CAT for the ECM?

Thanks guys!! I was always under the impression that the CAT's on 04.5 up had some kind of ecm junk on them. Sounds like I gonna get a new delete pipe soon
