Question 4" exhaust pipe behind Cat?

I am going to go install 4" exhaust pipe. My question is can I get away with going 4" after the Cat only? I want to also install gauges as soon as I can decide what type, a lot of them to choose from, and of course everyone of them are "THE BEST ON THE MARKET." And sometime soon a tuner.
I have a 2005 F-250 6.0L and will be towing a 32' fifth wheel travel trailer, which, by the sticker on the trailer says the max weight loaded is around 13,888 lbs. All though I'll never load that much in it to get close to that number.
The only things I have done so far is install a coolant filter system and will be installing Firestone Air Bags tomorrow.
Any help or advice from anyone else will be greatly appreciated!

i wouldnt waste my time with a cat back system, i dont see any benefit from it. I would buy a turbo back system and be done with it, the bigger down pipe should lower your EGT's

Agree completely. Go turbo back or not at all. There's not any real major benefit to just a cat back installation as opposed to a turbo back.

I have about the same set up, i pull a 14k 5er and before you do any mods get gauges they are a must because the ones on the dash just take up room and look good when the move it is to late. I installed the Edge insight it is a must when you pull look here.

This is the New Edge Insight the one i have they no longer make
EDGE 83730 Insight CS (Fits 1996 and Newer OBDII-Enabled Vehicles)
or this is the one that i would get bigger is better but if i got it my wife would kill me
EDGE 83830 Insight CTS (Fits 1996 and Newer OBDII-Enabled Vehicles)
The pyro, that is a must if you pull or not
EDGE 98601 EGT Accessory for CS and CTS (non-expandable)
Then you should get a Fuel pressure gauge because fuel pressure under 45lbs at WOT will kill injectors mine with 17k had 44lbs and 50 at idle now 62 at idle and 58 at WOT after the new Reg Kit.
After the gauge install if your temp spread is less then 15* do a coolant flush this is a must then install ELC coolant
Hope this helps there is alway more
