4" or 5" exhaust?

[strokr06]

Will a 5" cause turbulent, or clearance issues???
Will it attach to my 3.5"downpipe or is that replaced
With a 4"? I want a 5" for the deeper tone only but dont
Wanna cause any issues I have a b&w gooseneck hitch
As well. I figured someone on here has this set up and

i dont have a gooseneck hitch, but i must assume you should be fine with 5" . it clears fine just about everywhere , i know because i have 5". there is no power gain from it though, that i know of. let me know if i can help get you a system.

My 5" flo pro fits nice with the B&W hitch. No rubbing at all and it went together smoothly. 5" sounds deeper and doesn't improve/decrease power. Bolts to stock downpipe.

 

[strokr06]

Sounds good thats what I wanted to hear. I believe
A 5" is gonna sound the best but wasnt sure about the
Clearance's and hitch issue's and know if it would cause more lag from turbulent issues:thumbsup:

5" here and no clearance issues with B and W.

Plus a 5 inch will keep your egts lower.

 

[Horns07]

I have the five inch also and was surprised it all fit really well even with my B&W

I have a 5" but I have a different hitch setup. It rubs but not enough to bother me I'm going to fix it though. Other than that no issues.

The only difference you can tell between 4" and 5" is the sound, plus the downpipe is the same size with either kit, which is 4", so no, 5" will not lower egt's more than 4".

Im hoping the 5" is just a much deeper tone than the 4"
I really like the 4" as well just wanna try for a deeper note.
With all that being said if I go with the 5" its gonna have to be aluminized (flo-pro $359). If I get a 4" it will be S.S.
(Flo-pro $336) I have to stay under 400$ cause grabbing the egr delete kit at same time and wifes got me on a budget 5" stainless all seem to be atleast 550$

 

[strokr06]

Do any of you guys with the 5" wish you had gone with the 4" at all?? Do you think a 5" is worth sacrificing stainless steel for the aluminized??

 

[ghohouston]

Imo, 5" sounds better than 4" on any turbo diesel.

 

[Super08Duty]

If possible I'd go with a 5" stainless kit. It'll last longer and look better than aluminized.

 

[John@Outlaw_Diesel]

Go with the 5", sounds a lot better IMO. That's what I have on my 6.7. I have installed 4" and 5" with and with out mufflers. So far I like the 5" straight pipe the best.

 

[strokr06]

Does anyone wish they had gone w 4" instead of 5"?
Im not sure the stainless is gonna be any better than aluminized cause we dont get salt in the winters????

Neither do we, but over time is looks better. Doesn't rust and discolor as bad as aluminized.

get stainless. what egr delete did you get ?

 

[strokr06]

Sinister egr delete kit. I found a flo pro 5" for 359$ shipped free think that's gonna be my winner. I was
Always told if you weren't running 600hp a 5" was to
Big. IDK I only want the 5 due to deeper sound but
Dont want performance to be lost by not going with
The 4" s.s.
