Nissan Xterra 2015 Full Xterra headers, custom-made by Bin Mardah. Fox muffler, no bends, called a "joint" (mushteraka), best and smoothest sound. Softening mufflers were added to the "Y" pipe by Al-Safadi. And a final connector for a VXR. And the headers, praise be to God, are sound in all aspects.
