What size exhaust piping should i go with for my turbo setup? I will be boost around 7lbs. Some say 2.5" is fine, some say go with 3"...What's best for 7lbs of boost. Also, which muffler sounds the best with a turbo engine? I'm looking for something a lot quieter than my N1. I've looked at MagnaFlow. Are they any good?

 

3" is where it's at for turbo.

 

if your only boosting 7 pounds run 2.5.

wise ***.

 

Even at 7psi I would go with a 3" if possible. I am a fan of the Apexi n1 cannisters.

 

I'd defenitly go with 3" piping

 

any need to go bigger when boosting 15-23psi? or will 3" flow enough?

 

OH no. 3" will definately be fine for 15-23psi.

 

how bout 2 and 3/4

 

go 3" cause boost is addicting and before u know it ur gonna be boosting more than 7lbs so u wouldnt have to get new piping

and go with the apexi n1, thats what im running :D

 

Oh yeah. I was boosting ~15psi - ran 3" piping. Great spool up time.

 

bigger isn't always better, expecially if your going to run 3 inch all the way from the turbo to the intercooler to the TB the area between 3 and 2.5 adds up.

i run 2.5 , personally i think on 10 pounds it is even overkill. do as you please.

We are talking exhaust piping, not intercooler piping. 2.25" is fine for 450whp and I use 2.5" for up to 650ish.

I was planning on running 3" all the way around for running 15 psi daily, up to 23 psi when I feel like paying for real gas! You think 2.5" for the exhaust with that much boost or were you only referring to the other 10psi question?

yep reading skillz own me once agian. expletive!

yeah 3 inch for turbo exhaust. the greater the presure diffferential accross the turbine better spool time and turbo response. **** run with no DP if you could..

reading owns me while at work!!

 

2 1/2" or 3" will both be fine for your application. We went from stock to 2 1/2, to 3" then to 4". If you event think you will want to increase power in the future go with the 3".
