Verify inlet and outlet flange style, offset configuration, and overall length against the original exhaust before installation. This muffler assembly uses a 2-bolt welded flange and pipe connection inlet arrangement with a 2-bolt welded flange outlet, so matching the factory connection points is important for proper alignment on the Nissan Titan. Confirm clearance around the exhaust path and inspect adjoining pipes, hangers, and flanges for wear before assembly.
