Just out of curiosity....does a CAT delete really make that big a difference in MPG on these 6.0 rigs? I don't want to remove the muffler or replace the existing pipes.....but wondering if the cat test pipes help or not from an MPG perspective. My exhaust (2004) is all stock and I don't want it louder....just want more MPG and/or possibly more power.
And got me to thinking....sure would be smart of some entrepreneur to create a "test" pipe that has a cat look to it but really is a straight pipe inside. Would pass the visual inspection at least.
