Exhaust question
- Thread starter zainanderson
- Start date
I liked my 5" but it makes it tight to keep a spare tire. Also 5" is not as loud as 4" and it will help keep egt's a bit lower.
"What is better" is entirely subjective to the person posting the reply. Whats important to you? Loudness? Drone at highway speed? Grade of stainless? etc, etc, etc....
Do a search, as this subject has been talked about at length in the past. There are many companies who make decent exhaust systems.

5"is louder and drones more than a 4" and does nothing for egts. Its all really what you like, its 99% appearance. I personally go 5" bc I lift my trucks and run 35's so a 4" pipe looks dinky on my riggs...
I personally like flopro exhaust systems in aluminized, they fit very well and do not rust at all...
X3 it's all preference. I had a 4" then installed a 5" a few years later.
If you're on the fence about it I would go with a 5" b/c you'll want it eventually.
The 5" is louder and drones more than the 4" I had before. I'm glad I upgraded to 5" as well.

So if I straight pipe it 5" back my egt will still stay the same

I run a stack because the hot air rising vertically from the stack creates an updraft which creates a vacuum in the exhaust pipe which in turn helps to spool the turbos faster and decreases EGTs. Science. 4" or 5" won't make a difference. Just pick what you like and go with it. My suggestion is that if you're debating then go with 5" or you might kick yourself later down the road.
Plus the venturi effect if your stack is aligned properly with the top of the cab, double science.
I have an OldSkool Carbon stack with built in venturis. It also helps create downforce at the track.
Stack also helps when it gets deep. At that point the height of the air intake becomes an issue.
Oh I would say we are way over the intake with the shit. It looks to be coming out of every end. Good thing we have turbos that can chop it up into compost.
