Cher I decided to listen to your advice, I'm not going to cheap out on that exhaust.

So I'm trying to decide what to do. Like I said I want this quiet. So I have a few things to decide on. What I do know is I'm going to run 3" all the way until it splits for dual. That point and on is where I'm unsure.


Dual 2.5 or dual 2.25? some info I've been considering:
The surface area of a 2.25" pipe is 3.97"
The surface area of a 2.5" pipe is 4.90"
The surface area of a 2.75" pipe is 5.93"
The surface area of a 3" pipe is 7.06"
The surface area of a 3.25" pipe is 8.29".
The surface area of a 3.5" pipe is 9.61".

So if I split to dual 2.25", the surface area is 7.9". which is about the same as a 3.25" single.
If I split to a dual 2.5", the surface area is 9.8" which is about the same as a 3.5" single.

Advantage of going 2.25 is slightly less cost, easier to route.
Advantage of going 2.5 is more flow (but do I really need it?).

Ant experts out there have any thoughts on that?
