Plus, I have also been told by a few people that with the light mods that I am going to have, that there will not be that much back pressure on the turbo. So therefore it will not spool up as fast as it would with the 4". 
I am looking for any help that anyone can give me in making this decision.
Also, are these statements that I mentioned above true?
Thanks in advance for the help.  |
I have a 5in back and i love it but if you do not plan to heavily mod it then i would use the 4in back.
There is never too little backpressure in a diesel. in my experience when the charger spools you will build more psi when there is less backpressure, however it may take a very small amount of time longer to spool up. just my experience though
