4" or 5" exhaust
 

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:pca1:

4in verse 5in
 

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 shit 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 :tu:

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

Ya I'm a first gen in a blazer I'm all stock for now but I do have plans to twin turbo it down the road studs fuel pin u name it but I just like the sound of a 5":rocking:

i just built a 5 inch tail pipe for mine out of junk i had laying around the shop. turned out pretty good. mine goes from 3in to 4in to 5in lol someday ima run 4in back past the tcase then go to 5 in

Put up a pic I wanna see how u did it

Sounds like mine, 3'' dp to 4'' under cab to 5'' stack. :choochoo:

alright il try and get some pics up soon
