Dual Exhaust Functional setup.. Crushed..
HEy all,
I'm going with the Dual exhaust setup (of course for looks)...
I will have the Y after the Resonator (at the first bend in the pipe)...
From the Header back to the Y i'll be running 2.5" piping...
Now, I am only able to get the Crushed piping from the Y-back to the Tail...
So instead of going from 2.5" at the Y to 1.25" (like i should with a Manderal bend)
What size do i use because of the crushes?
1.5", 1.75", 2" ?
Thanks all

why are you getting 2.5 in the first place. the biggest you want to go (unless ur running a turbo or sc) is 2.25. I had a dual setup on my last car, and just ran crushed 2.25 'til the y, then crushed 1. 25. worked fine.

heres a quote from another guy...
thoughts?
Total cross sectional area of 2.5" exhaust = ~4.9085".
Total cross sectional area of 2 1.25" pipes = ~2.45".
Total cross sectional area of 2 1.75" pipes = ~4.8104".
Total cross sectional area of 2 1.76" pipes = ~4.9087".
You see, just dividing in half isn't the answer. You will need 2 pipes of ~1.76" each, as 1.75" is still going to be too small. And that's if they are mandrel bent. If you are getting crush bent piping, then you will need a muffler shop that can estimate the inside diameter of their crush bent piping, and then calculate the cross sectional area.
