Up for sale is a 2 1/2" - 3" stainless steel cat-back exhaust for '05-15 Xterra. I ran it for two years on my 2014 Xterra and added a Vibrant 1142 resonator at the exit to eliminate drone at cruising speeds. Direct fit, no mods needed, uses factory installation points.
Note: exit tip points directly downward; rear section is laying sideways in photos.
