Bolt on mod tips

[Vincenzo]

Okay guys i'm new to the forum and new to the diesel truck world period. I have a 06 F350 King ranch. I'm looking to do some simple Bolt on mods and was looking for some opinions. I want to do exhaust and cold air intake right off the bat. What are the advantages/disadvantages of 4" compared to 5" from turbo. Can i legally cut the cat out? Also whats the best cold air intake for the money i have always used K&N.... Also if there are any other mods i should do i'm open for suggestions!

Thanx,
Vinnie

The stock airbox is good to 500hp. As for 4" vs. 5"...pretty much gonna be the difference in tone.

"Legally" no you can't but most on here that have done exhaust have the cat deleted including me. 4" is plenty big for the exhaust. The intake I would leave stock. It flows plenty of air to support 500 HP and filtes a lot better than most aftermarket systems.

for emmisions leave in the cat, if not then take it out, exh and then a SCT and you will fall back in love with your truck

like other people said.. legally you have to have the cat on... but i would say 90% of the people that do an exhaust kit take it out... as far as the intake goes the stock will flow more than enough air... only reason to change it out for a aftermarket CAI is for ease of taking out the filter to clean.... my recommendation is either the S&B or AFE stage 2

were running an exhaust sale right now if your interested

I would spend the money on making it bulletproof first , like EGR delete or blockoff , it can be done if you have to leave it on for emissions just a little trickier..
It would be a bummer to make the truck run better only to have the EGR puke coolant and push your HG's

Get rid of the junk Ford "gold" coolant. Flush the system and fill with a good ELC coolant (EC-1 rated) and install a coolant filter system. I am in the process of getting the coolant filter so I can switch mine over. There are plenty of threads on here about why to switch coolant.

This is in PGreenSVT's sig.
Replaced oil cooler still difference in temps

do exhaust,sct,get some type of gauges most everyone goes with the edge insight and do the ELC coolant and coolant filter

Thanks for all the quick responses guys! So ill prolly nerf the Intake idea and go with a off road exhaust with no cat. so what is the sound diff between 4 and 5"? thanx for the coolant change tip i am going to research into that further. I don't know if i want to to a chip or programmer because i don't want to do anything that is going to hinder the overall life of my truck or tranny. As far as gauges go is digital the way to go? I really appreciate the advice guys i am a noobie so be on the lookout for more questions!
