mines 3inch from the cat well where the cat was.... i think i havent looked at it since the summer
but its 40 series flow master its loud as hell and smells like a 60s-70s car. ill take some pics on tue when i work on it

ive been told the best way to do true dual would be to remove or cut the side skirts and runs it right out behind the front tires but ive never seen it done and im sure there would be clearance issues
