looking for noise!

I have a 2007 6.0 powerstoke and i am new to diesel mods and was looking for a little advice. I am stuck between a 4" and 5" straight pipe. I want alot of turbo whistle.. so which one should i go with? Also looking to get a cold air intake, but ive been told deisel engines dont like the high flow filters. Any help would be greatly appreciated.

unless you are planning to do motor work, a 4" should be fine, i have a S&B on my truck, it didnt add much, but it doesnt take me half an hour to change the fing air filter any more.

for a loud whislte, find an 03 turbo

If its straight piped you will get a lot of whistle regardless of whether you use 4 or 5 inch. At WOT they will have a somewhat different tone. 5 inch is deeper and throatier, 4 inch is a little more raspy. I had both and really preferred the 4 inch overall. Don't waste your money on an intake unless you have the parts to make over 500hp, the stock intake is great up to there. Use that money on gauges or an EGR delete or something.

Even without the 500hp would a cold air intake increase the sound and performance at all. If so would you recommend AFE?
My truck had EGR cooler welded off when i bought it and i almost lost my warranty! I want to stick with mods that dont leave any evidence or give me CEL problems.

4in IMHO sounds better. Buddy has a straight piped 5in and it sounds like a garbage truck unless he gets on it.

Intake is a waste of money for a stock 6.0. The stock airbox flows great. I noticed zero difference on my 04 with am AFE. Except it was easier to service the filter.

You may be able to hear the turbo a little more? I bought my intake before I had any real knowledge on the 6.0 in 05. But from a performance standpoint, you won't gain much of anything really. I have an AFE and have no experience with anything else so thats what I would recommend if you are set on buying one. Gauges won't give you any warranty problems and will be much more beneficial from a monitoring standpoint than an intake.

Well i think im pretty much set on the 4" straight pipe and i know the intake may be a waste of money but i really want all the turbo sound i can get!!! Would an AFE stage2 trigger my MAF sensor and throw a CEL? or can the sensor be unplugged?.. and im def gonna get gauges.

You want turbo noise, find yourself an 03 turbo.

Shouldn't throw any codes.

I put my cold air filter kit on my truck before the cat and muffler fell off and I could tell a difference with my turbo spooling up quicker and running better.
