I'm in the middle of my project and I want to run 5" but my buddy keeps saying 4" is better so I wanted to hear everyones input

 

well my names daniel i have a 93 12v and i just put diamond eye 4in all the way back no muf and let me tell u holy **** a friend of mind has a common rail with 5in but he has 600 to the wheel i probly have3 to350 from what ATS saids what pump do u have

 

untill you reach about the 500hp level the 5 inch exhaust will actually hurt power output, not a lot but enought to notice on a dyno, if your goals are to reach that power then go for the 5 inch because i always hate buying parts twice ya know

 

with a ve pump correct? unless youve got twin turbos, 5" exhaust is just a way to spend more money.
