i have one on my coupe, it will fit but you have to have 2 extensions made because the 350z is about 7 inches shorter than the G, other than that the hangers are still in the same place, oh yeah, i also had extensions welded in to make it a little longer because it was too close to the rear bumper and i didnt want it to melt. you can search previous posts by ducatiguy and he posted a video clip of my exhaust.
