So will the elimination of the Cat and muffler on the '04 6.0's do a lot for performance?
I looked under my truck and didn't notice and exhaust sensors. Will it help or hurt in the long run?
it helps alot and it makes the turbo whisle loud and the cat back its just bolted on it help me because i am running a max microtuner and not trying to be mean but if you have a hearing aid it may hurt your ears i dont know but when you pass buildings and cars it whisles loud and i didnt think it had a gate on it anyway

Federal law prohibits removal of the cat. Gale banks did flow tests on the cat and reported there is no restriction in the cat. Most have been cutting the inlet and outlet pipe at the point where it will fit a 4" pipe and weld it into the system after it is installed.
The removal of the muffler and replacement with a performance muffler or straight pipe if you can stand the noise will help a lot they say. Mine still has the stock exhaust and with the Predator on 100 HP and A K&N FIPK my dyno sheet on my gallery shows it makes plenty of power.
Some say they pick up as much a 2 MPG improvement in mileage witha 4" system. It would take lots of tanks of fuel to pay for it.
I think it comes down to being able to say mine is bigger than yours. By the way, I plan to put one om mine as soon as it cools off here in Texas, but you know what I mean!
My point precisely. Maximum performance. Don't overspool that turbo though! Plus performance shops are in the business of selling product and would love to sell you another turbo.
Here is another thought. The outlet flange on the turbo is 3.5 inches. Anything larger than that will not help flow and could induce turbulance which would actually restrict flow.
