Oh I have another question that I can't seem to put my finger on. From what I'm reading the exhaust size I should for a stock turbo is 2.5" right? How come not 3", I'd figure that 2.5" would be to small, I have 2.5" on my 3.0L V6 ranger. So I mena on a turbo id' think I'd go bigger. Also I'm looking around at the FMIC and people say 2" piping from the turbo to IC and then 2.5" after that. Is this correct" I just want to get most of my questions out of the way.
