Sterling Posted November 19, 2019 Share Posted November 19, 2019 I am thinking about running duals of my 2nd gen pathfinder that is a 2001. what is the diameter of the pipe right after the catalytic converters? as well as muffler suggestions, I am planning to do some thrush welded mufflers for it. I have the 3.5 liter v6 3500 motor! Link to comment Share on other sites More sharing options...
