I have a 96 f350 and I already have a 3dp to a 4 pipe to a 5 in tip but im wanting to go to stacks I just don't know what size and if it would be worth it any suggestions? pros/cons?

 

A stack is a stack, only thing a bigger one will do is give you a different sound and cost more money

 

The stack is gonna make it harder to talk to the person riding with you in the cab too.
We just got done cutting the 5 inch stack off my buddy's cummins and running 4in straight pipe out the back because it was unbearable in the cab

 

I know depending on stack like if you went dual with Aussie tips so its somewhat pointing away. I got a 7 inch mitre cut that comes from 4 inch piping just haven't put it on yet. I went with a 5 inch MBRP even though I am obsessed with wanting stacks. I haven't been disappointed yet with the MBRP 5 inch turbo back. So for stacks I'd say base it off of your wheels so they don't look tiny. As for piping into the stack I wouldn't go over 5 inches
