How many of you are using a 3" down pipe with your turbo 6.0 set ups?

 

I would say most people run 3" but bigger is better

 

i run a 3'' on my turbo'd 6.0 but im putting a 3.5 dp and 3.5 piping all the way back as soon as i have time. im curious to see if theres any difference in power. i did notice more power going from a 3'' magnaflow to a 4'' diesel muffler even though the rest of piping is 3''

 

3" has been proven to make 700. To the ground.

And it's not just the size but routing radius using etc.

You planning on dyno or track testing the 2 different pipes?
