Im doing a side exit exhaust on my 1999 3.0l v6 ranger. Im taking out the cats and putting in a flowmaster 40 series. I just need to know what size flowmaster to get. Is there a plus of having two different sizes of in and out on a flowmaster. Is like 2 inch or 2.5 better, or any size. I dont want it to big to loose back preasure.
w/ your 3.0 run 2.25" piping. I disagree w/ the anti flowmasters on the basis that most people get a damn muffler for the sound(atleast on a 3.0 ranger). You wont loose any power over stock using a flow
