Installation Notes

Verify inlet and outlet configuration, flange style, and overall length against the existing exhaust assembly before installation. This muffler uses a 2-bolt welded flange inlet, pipe connection inlet and outlet points, and an offset configuration, so alignment with the vehicle’s exhaust piping is important for proper fit. Confirm compatibility with your specific Nissan Xterra or Nissan Pathfinder year before ordering.
