Exhaust System Advice

Looking at doing a turbo back dual exhaust kit for my '08 350. Im going to attempt to custom fab some tips to fit through the (unnecessary) cutouts in my Smittybilt M1 rear bumper. A few questions:

1. Is there a huge difference in 4" and 5" pipes?
2. If i do 4" pipes do i really need to do a turbo back swap since the factory is 4" (i believe?)
3. What brand, if any one brand is better than the other?

6.4L V8 Turbo Diesel
DPF/CAT delete

AFE Stage II R5

Strokin' since the start.

Difference between 4" and 5" is just sound unless you start getting real real high HP and then you need the flow of a 5.

All downpipes are 4". The stock downpipe is super constricted, I would change it no matter which you decide.

The only difference in brands you will find is material and maybe fitting a little easier or harder. Nothing a little elbow grease can't fix. Also as far as material, in Texas with no salt on the roads doesn't really make a difference. Aluminized holds up fine. Unless you really want to spend the extra coin on stainless just because.

Look thru the site sponsors and give one of them a call. They might be able to find you a discount for you being an org member.

Here's the diffrence between the 4" and the 5", if you get the 4" your always gonna wonder if the 5" would have been better.If you buy the 4" your gonna always be thinking about the 5" and be asking yourself- Would the 5" perform better? Would your egt's be 25* or 35* or even 50* lower? Would it sound tougher when you romp on it? Would your dog still have run away if you had the 5"?Would you be able to get a lower mortgage rate on the new house if you had a 5"? Would your Doctor insist on that extra prostate check up if you had the 5" system.....well okay you get my point. Go with the 5 and never look back.

Hahaha that's funny. For what it's worth I run a 5", but I'm never happy with the HP I have and want more... But power and EGT wise there won't be a noticeable difference until you are at 600+hp. There is a definite sound difference tho. The 5 has a deeper tone to it.

Yes ol' Jed (my redbone coonhound/black mouth cur mix) does.

Love the sound of your exhaust by the way. Just watched your YouTube vid.
