This muffler assembly uses an offset inlet and offset outlet layout, so alignment with the vehicle’s exhaust hangers and pipe routing should be checked during mock-up. Confirm whether the vehicle is equipped with the Federal Emission System or California Emission System when selecting the 2000 Nissan Xterra application. Professional exhaust installation is recommended for proper fit and sealing.
